Write the expression of the Kb of the weak base methylamine CH3-NH2
(Kb = 10-4)
b. Calculate the pH value of a solution that contains 0.31 g/L of methylamine.
c. Calculate the pH of the above solution after the addition of 0.01 moles of
HCl.
d. 0.01 moles of HCl are added to a solution that contains 400 mg/L of NaOH
. Calculate the pH of the solution after the addition of the acid.
Assume that the initial volume remains unchanged after the additions
AM C = 12, H = 1, N = 14, Na =23
