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 HF is a weak acid. 0.7 mol of NaOH is added to 1.0 L of a 0.4M HF solution. 0.14 mol of NaOH is added to 1.0 L of a solution that is 1.4M in both HF and NaF. acids: bases: NaOH other: HF.H.OH.N.F acids: HF,H bases: NaOH, OH other: NaF, Na L G

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 HF is a weak acid. 0.7 mol of NaOH is added to 1.0 L of a 0.4M HF solution. acids: bases: NaOH X 0.14 mol of NaOH is added to 1.0 L of a solution that is 1.4M in both HF and NaF. other: HF.H.OH.

A solution is prepared that is initially 0.30M in hydrofluoric acid (HF) and 0.13M in potassium fluoride (KF). Complete the reaction table below, so that you could use it to calculate the pH of this solution. Use x to stand for the unknown change in [H3O+]. You can leave out the M symbol for molarity. [HF] [F] [H,O] initial 0 0 change 0 final 0 0 ㅁ 1 G
