Textbook Question
Acid and base behavior can be observed in solvents other
than water. One commonly used solvent is dimethyl
sulfoxide (DMSO), which can be treated as a monoprotic
acid 'HSol.' Just as water can behave either as an acid or a
base, so HSol can behave either as a Brønsted–Lowry acid
or base.
(b) The weak acid HCN has an acid dissociation constant
Ka = 1.3 * 10-13 in the solvent HSol. If 0.010 mol of
NaCN is dissolved in 1.00 L of HSol, what is the equilibrium
concentration of H2Sol + ?
