For the general equation of a weak acid, you need to solve for the Ka value. To do that you use. Ka = [H3O +][A −] [HA] Another necessary value is the pKa value, and that is obtained through pKa = − logKa. The procedure is very similar for weak bases. The general equation of a weak base is. BOH ⇌ B + + OH −.Q. The ratio of moles of A to total number of moles present in 150 mL of 20% (v/v) solution is 0.3. Density of the solvent is 0.12 g/mL and molar mass of the solvent is 14.4 g/mol.
