QuestionIonic equilibrium / Henderson equation
Which one of the following is the correct form of Henderson’s equation for calculating the pH of a weak acid solution containing its salt ?
- (a) pH = pKₐ + log \(\frac{[acid]}{[conjugate\ base]}\)
- (b) pH = pKₐ + log \(\frac{[conjugate\ base]}{[acid]}\)
- (c) pH = pKₐ − log \(\frac{[acid]}{[conjugate\ base]}\)
- (d) pH = pKₐ − log \(\frac{[conjugate\ acid]}{[base]}\)
