b. Use the information in the first question to calculate the pH of a 0.10 M solution of iodic acid at a temperature of 25 °C?

c. Use the information in the first question to calculate the pH of a solution obtained by combining 20.0 mL of 0.10 M iodic acid and 10.0 mL of 0.1 M sodium hydroxide (NaOH).

d. Use the information in the first question to calculate the pH of a solution obtained by combining 20.0 mL of 0.10 M iodic acid and 20.0 mL of 0.1 M sodium hydroxide.

Appriciate it!

Expert Solution

1) ans Ka * Kb = Kw

1.6 * 10^-1 * Kb = 10^-14

Kb = 0.625 * 10^-13

b) P^H = - log [ H+]

= - log 10^-1

= 1
