QUESTION 1

What is the pH of a buffer that consists of 0.2 M CH₃CH₂COONa and 0.528 M CH₃CH₂COOH? K_a of propanoic acid, CH₃CH₂COOH is 1.3 x 10^-5

QUESTION 2

Calculate the pH when 1.79 g of CH₃COONa is added to 19 mL of 0.50 M acetic acid, CH₃COOH. Ignore any changes in volume. The K_a value for CH₃COOH is 1.8 x 10^-5.

QUESTION 3

Calculate the pH of a solution that results from mixing 38 mL of 0.14 M methylamine (CH₃NH₂) with 16 mL of 0.1 M CH₃NH₃Cl. The K_b value for CH₃NH₂ is 3.6 x 10^-4.
