![]() ![]() Ī high-pressure version of deuterated carbonic acid, i.e. Pure carbonic acid is mainly produced in two ways: the proton-irradiation of pure solid carbon dioxide and by reacting hydrogen chloride and potassium bicarbonate at 100 K in methanol. In the presence of water, it decomposes to form carbon dioxide and water, which further accelerates the decomposition. Carbon dioxide can be described as the anhydride of carbonic acid.ģ, is quite stable at ambient temperatures as a gas. 6.8, at equilibrium carbonic acid will be almost 50% dissociated in the extracellular fluid ( cytosol) which has a pH of ca. Strictly speaking the term "carbonic acid" refers to the chemical compound with the formula Hģ however, some biochemistry literature uses the term to incorrectly refer to dissolved carbon dioxide in extracellular fluid. Use of the term carbonic acid Speciation for a monoprotic acid, AH as a function of pH In physiology, carbon dioxide excreted by the lungs may be called volatile acid or respiratory acid. When Henry's law is used to calculate the value of the term in the denominator care is needed with regard to dimensionality. The value of log β 1 decreases with increasing ionic strength, I In the following expressions represents the concentration, at equilibrium, of the chemical species H +, etc. The stability constants database contains 136 entries with values for the overall protonation constants, β 1 and β 2, of the carbonate ion. It has been estimated that the increase in dissolved carbon dioxide has caused the ocean's average surface pH to decrease by about 0.1 from pre-industrial levels. Įxpected change refers to predicted effect of continued ocean acidification. The acidification of natural waters is caused by the increasing concentration of carbon dioxide in the atmosphere, which is caused by the burning of increasing amounts of coal and hydrocarbons. The Bjerrum plot shows typical equilibrium concentrations, in solution, in seawater, of carbon dioxide and the various species derived from it, as a function of pH. In aqueous solution carbonic acid behaves as a diprotic acid. ![]() Chemical equilibria Equilibrium constant values Bjerrum plot for carbonate speciation in seawater (ionic strength 0.7 mol dm −3) In biochemistry and physiology, the name "carbonic acid" is sometimes incorrectly applied to aqueous solutions of carbon dioxide, which play an important role in the bicarbonate buffer system, used to maintain acid–base homeostasis. The interconversion of carbon dioxide and carbonic acid is related to the breathing cycle of animals and the acidity of natural waters. The molecule rapidly converts to water and carbon dioxide in the presence of water however, in the absence of water, contrary to popular belief, it is quite stable at room temperature. If the 25.00 mL sample that was titrated had been produced by dilution of a 10.In chemistry, carbonic acid is an organic compound with the chemical formula H 2 C O 3.If 37.63 mL of thiosulfate solution were needed to titrate a 25.00 mL sample of an acid, what was the H + ion concentration of the acid? The thiosulfate solution was determined to be 1.023 M. ![]() The endpoint is reached when the solution becomes colorless. The amount of iodine produced from this reaction can be determined by subsequent titration with thiosulfate: 2S 2O 3 2+ + I 2 → S 4O 6 2− + 2I − Starch is used as the indicator in this titration because starch reacts with iodine in the presence of iodide to form an intense blue complex. ♦ A method for determining the molarity of a strongly acidic solution has been developed based on the fact that a standard solution of potassium iodide and potassium iodate yields iodine when treated with acid: IO 3 − + 5I − + 6H + → 3I 2 + 3H 2O If the overall reaction sequence was 75% efficient, how many grams of carbonic acid were initially dissolved in the 250 mL to produce the calcium bicarbonate?. ![]()

![]() OLEDs work by sending an electric current through a layer of organic materials. OLEDs are used in a variety of electronic devices, including televisions, computer monitors, and smartphone screens. They are made of an organic material that emits light when an electric current is passed through it. How do OLED Images Work?Īn OLED is a thin, light-emitting diode that creates an image. They offer many advantages over traditional LCDs, and their thinner, lighter, and more energy-efficient design is especially appealing for mobile devices. OLED images are becoming increasingly popular as display technology improves. AMOLEDs are used in high-end devices such as smartphones and TVs, while PMOLEDs are typically used in lower-end devices such as MP3 players and digital cameras. There are two main types of OLED images: active-matrix OLEDs (AMOLEDs) and passive-matrix OLEDs (PMOLEDs). ![]() ![]() OLED displays also have better contrast and faster response times than LCDs. This means that they can be thinner and more energy-efficient. OLED displays are different from traditional LCDs because they don’t require a backlight.

The opening stage directions to Ibsen’s Hedda Gabler looks like this: All the same, many actors and directors favour P and OP as they eliminate the sometimes-confusion of having to clarify which person’s left or right is being spoken about. Prompt corners are still common features in modern theatres, although their placement to stage-left is not always guaranteed. ![]() More a staple in British theatre, they refer to the “prompt corner” traditionally occupied by the stage manager to the left side of the stage-a nook where actor’s could be safely prompted if they forgot their place in a play. ![]() One important variation of this convention is the use of “prompt side” (P) and “opposite prompt (side)” (OP), which are alternate names for stage-left and stage-right. So now when you read the stage directions from Look Back in Anger by John Osborne and read the following in Act 1: “(He walks C., behind Cliff, and stands, looking down at his head.)”, you know that you have to move from where you finished you last line to centre stage and peer down at the other actor sitting in the chair! Easy, right? It can be a little confusing at first, but with practice it becomes second nature. Left and right correspond to the actor looking out at the audience. They are always given from the actors perspective-upstage being towards the back of the auditorium and downstage towards the audience. These are actual terms used in the theatre to describe the various positions on the stage. You may have heard of the idea of “stage left” or “centre stage”. By learning the different types of stage directions, you’ll get a better sense of what the author was trying to convey in writing them down, and how they may help you in your performance. Sometimes, they’ll be of more use to the director, design team or the dramaturg. One thing to keep in mind is that while you’ll likely read every word written down in the script, not all stage directions may be relevant to you directly. ![]() Other times, it’s more descriptive of the world of the play, allowing you to conduct analysis as to how you might bring words off the page and into life. Sometimes, it’s purely for the ease of blocking a scene-working out where the actors stand and how they’ll move around the space. Types of Stage Directionsĭifferent types of stage directions will give you different types of information. Tennessee Williams, on the other hand, was incredibly descriptive, outrageously prescriptive and wrote genuine essay-length stage directions! Each writer has their own style, and it is your job as the actor to know what these instructions mean and how to make them work for you on stage. Shakespeare was famously very light on the stage directions, his only credited one is ‘Exit stage left, pursued by a bear’! This is because he was acting in or directing his own pieces and didn’t need to write down the stage directions. They also give you an insight into the playwright and how they approach their work. Stage directions give you vital information for the action and relationships between people, things and places inside a text. It is the stage directions that tell you what a character looks like, where they travel in the space and what the space looks and sounds like. Stage directions are instructions in a play for technical aspects of the production, such as lighting, sound, costume, scenery or props and, most importantly, the movement of actors onstage. What are these italicised commands? And how can you, as an aspiring actor, make sense of them? Separate the wheat from the chaff? The Tenessee Williams from Eugene Ionesco? The answers are contained below, so read on to uncover the mysteries and intricacies of stage directions in theatrical productions!

Invicta purchased all the rights to the game and the founder, Edward Jones-Fenleigh, refined the game further. After presenting the idea to major toy companies and showing it at the Nuremberg International Toy Fair, it was picked up by a plastics company, Invicta Plastics, based near Leicester, UK.
