What is the pH of a buffer solution that is 0.150 M in hypochlorous acid (HCIO)

Question

What is the pH of a buffer solution that is 0.150 M in hypochlorous acid (HCIO) and 0.110 M in sodium hypochlorite The K_a of hypochlorous acid is 3.8 * 10^-8. 7.55 9.20 7.29 14.13 6.71 What is the [CH_3COO-]/[CH_3COOH] ratio necessary to make a buffer solution with a pH of 4014 K_a = 1.8 * 10^_5 for CH_3COOH. 0.25:1 1.1:1 4.0:1 0.87:1 Which of the following is TRUE A titration curve is a plot of pH vs. the [base]/[acid] ratio. At the equivalence point, the pH is always 7. An indicator is not pH sensitive. The equivalence point is where the amount of acid equals the amount of base during any acid-base titration. None of the above are true. What is the pH at the equivalence point of a weak acid-strong base titration pH = 7 pH > 7 pH = 14.00 pH

Explanation / Answer

I can only answer one exercise per question, if you want the answers to other questions, attach them to a new question, the last question compares the equivalence point between a weak acid and a strong base, the pH will be greater than 7.

the b) pH>7 is the correct.
