A buffer solution is prepared in such a way that the concentration of propanoic acid is 8.0 × 10−1 M and the concentration of sodium propanoate is 8.4 ×10−1 M. The buffer equilibrium is described by C2H5COOH(aq) + H2O(l) ⇌ H3O+(aq) + C2H5COO−(aq)propanoic acid proponate ion with Ka = 1.34 ×10−5. If the concentration of the sodium propanoate were doubled while the acid concentration remained the same, calculate the pH of the resulting solution.

Question

A buffer solution is prepared in such a way that the concentration of propanoic acid is

8.0 × 10⁻¹ M and the concentration of sodium propanoate is 8.4 ×10⁻¹ M.

The buffer equilibrium is described by

C₂H₅COOH(aq)	+	H₂O(l)	⇌	H₃O⁺(aq)	+	C₂H₅COO⁻(aq)
propanoic acid						proponate ion

with K_a = 1.34 ×10⁻⁵

. If the concentration of the sodium propanoate were doubled while the acid concentration remained the same, calculate the pH of the resulting solution.
