Question
A buffer solution is 0.100 M in formic acid (HCOOH) and 0.0500 M in sodium format (HCOONa). The ka of HCOO is 1.76 x 10-4 The ionization reaction of the acid is:
HCOOH (aq) + H2O = HCOO- (aq) + H3O+ (aq).
1. Calculate the pH of the buffer.
2. Calculate the pH by adding 20.00mL of 0.100 M NaOH to 200 mL of the buffer solution. PS: Write the stoichiometry reaction when the strong base is added to the weak acid.
c. Calculate the ΔpH after adding the base.
