Question

In a 0.10 M solution of ascorbic acid, 2.8% of the ascorbic acid will dissociate. Consider the pH you would measure for a 0.25 M solution of ascorbic acid. Which of the following statements is true?

a.) The pH would show that the % dissociation would be the same in both ascorbic acid solutions.

b.) The pH would show that the % dissociation would be twice as much in the more concentrated acid solution.

c.) The pH of the more concentrated solution would be lower.

d.) You must know the Ka value for ascorbic acid before determining which of the above selections is true.

Please explain your answer!

Explanation / Answer

b.) The pH would show that the % dissociation would be twice as much in the more concentrated acid solution.

because the dissociation would be dialation of the frontation. you see when 0.1 solution becomes the aswer, you will never find the real problem
