Question 1

A 4.5 x 10–3M solution of a weak acid is 6.3% dissociated at 25ºC. In a 4.5 x 10–4M solution, the percentage of dissociation would be:

◦ the same.
◦ > 6.3%.
◦ < 6.3%.
◦ zero.
◦ Need to know the Kaof the acid to answer this.

Question 2

A monoprotic weak acid when dissolved in water is 0.66% dissociated and produces a solution with a pH of 4.15. Calculate the Ka of the acid.

◦ 6.6 × 10–3
◦ 1.1 × 10–2
◦ 4.7 × 10–7
◦ Need to know the initial concentration of the acid.
◦ None of these are correct.
