Question

6 (2 of 15) A given molecule is predicted to have a pK of 6.8. Given this information which of the following statements is correct? O The molecule would be a good buffer to mimic physiological conditions found in the cytosol of most cells within your body OThe molecule will not be a good buffer at pH of 5.0 because the protonated form will be too low in concentration to effectively "buffer the addition of hydroxide. O The molecule will not be a good buffer at pH of 9.0 because the deprotonated form will be too low in concentration to effectively "buffer" the addition of protons. All of the above are correct.

Explanation / Answer

2.

Given molecule is predicted have pK 6.8

The molecule would be a good buffer to mimic physiological conditions found in the cytosol of most cells within your body.

3.

the physiological pH of the blood is maintained at a constant pH of 7.4 .One of the primary aspects of the buffering system for the blood is the diprotic acid carbonic acid whose pK is 6.1.

->At physiological pH H2CO3 conc. will be low & must be replenished by decreasing the respiratory rate (hypoventilation) if condition become more basic.

4.

1. Equilibrium constant =A. the ratio of product to reactant conc. for any given reaction

once the equilibrium has been reached

2. Ion product of water= D.The ratio of product to reactant conc. of water ionization

multiplied by the conc. of water

3.Conjugate base=C. the base formed when an acid deprotonates .

4. Midpoint =B.pH=pK
