The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that HCN is a weak acid. acids: Jn 0.0.... 0.02 mol of KOH is added to 1.0 L of a 0.2M HCN solution. 0 bases: S 0 other: 0.52 mol of NaOH is added 0 acids: 0 bases: to 1.0 L of a solution that is 1.4M in both HCN and NaCN. other: X
