14.3 Exercise 35

Calculate the concentration of all solute species in each of the following solutions of acids or bases. Assume that the ionization of water can be neglected, and show that the change in the initial concentrations can be neglected.

(a) 0.0092 M HClO, a weak acid

(b) 0.0784 M C₆H₅NH₂, a weak base

(c) 0.0810 M HCN, a weak acid

(d) 0.11 M (CH₃)₃N, a weak base

(e) 0.120 M $\text{Fe} \left(\text{H}_{2} \text{O}\right)_{6} ^{2+}$ a weak acid, K_a = 1.6 $\times$ 10⁻⁷
