Question 7

A buffer solution is prepared by mixing 150 cm³ of 0.40 mol dm^-3 propanoic acid, $CH3CH2COOH\text{CH}_3\text{CH}_2\text{COOH}$ , with 250 cm³ of 0.30 mol dm^-3 sodium propanoate, $CH3CH2COONa\text{CH}_3\text{CH}_2\text{COONa}$ . Given that $K_a\,$ for propanoic acid is 1.35 × 10^-5 mol dm^-3 at this temperature, what is the pH of the resulting buffer solution?
