Find the pH of a formic acid solution when the concentration of formate and formic acid are equal to one another. Why is the answer to the previous problem significant in regards to titration? A buffer is a solution which resists pH change even though additional acid or base has been added. Generally speaking, any molecule with an ionizable functional group can act as a buffer at its . What characteristics should a biological buffer have?

Provide the chemical formulas and the names of the three predominant carbonic acid species indicated by arrows in the image below: Species 1 species 2 Species 3 Explain i) how you can determine the pH range at which a weak acid/conjugate base system will display buffering properties.ii) what is the reason/logic behind the rule applied in i)? and iii) indicate the pH ranges of the carbonic acid system based on the pka values provided above. Provide the chemical equilibrium that describes the carbonic acid buffer system that exists at pH 9.3. Clearly indicate the chemical formulas, identify the weak acid and it’s conjugate base, and the names of the chemical compounds.

In the north-eastern part of a particular Caribbean island, in a valley close to a mountain range the water table tends to be high within the soil profile during the wet season. Soil and ground water samples were taken at various points within the water table region for analysis. The ground water was found to have a high divalent calcium ion concentration but a low oxygen concentration.(i) Predict the pH of the ground water. Explain your answer.
Explain how a solution of butanoic acid and potassium butanoate can function as a buffer solution. Your answer must include a brief description of how this buffer functions on the addition of a small amount of acid , a small amount of alkali and a small amount of deionised water..

What questions and topics where asked on the interview and how did you think you did? Converted to an essay question? This question is about a buffer solution made by mixing together solutions containing ethanoic acid and sodium ethanoate. a) If you add a small amount of an acid such as dilute hydrochloric acid to this, the pH doesn't change much. Explain what happens to the extra hydrogen ions you have added (think in terms of pkas, acid/base and conjugate acid/base). . b) If you add a small amount of an alkali such as sodium hydroxide solution to the buffer solution, again the pH doesn't change much. There are two ways in which the extra hydroxide ions can be removed. What are they?
When calculating your equivalent mass of the unknown organic acid, the volume used in your titration must be in what units?
