If the pH of a solution of magnesium chloride gets too high, magnesium hydroxide

Question

If the pH of a solution of magnesium chloride gets too high, magnesium hydroxide (insoluble metal hydroxide) could precipitate from solution. If you prepare a buffer solution, it is possible to prevent the precipitation of Magnesium Hydroxide by controlling the pH. Which of the following buffers solutions would not result in the precipitation of Magnesium Hydroxide from a solution that is 0.0173 M in Magnesium chloride . Check all that apply. Ksp for Mg(OH)_2 = 1.2 times 10^11 1.0 M HN0_2 with 1.0 M NaNO_2 2.0 M C_6H_5OH with 1.32 M KC_6H_5O 1.0 M HCN with 2.0 M NaCN 5.6 M C_6H_5OH with 1.0 M KC_6H_5O 2.0 M HCN with 1.0 M NaCN 1.0 M C_6H_5OH with 1.0 M KC_6H_5O

Explanation / Answer

A solution which would give a basic solution when dissolved would not be ideal for our case. Thus the ones which would not give precipitate would be,

1.0 M HNO2 with 1.0 M NaNO2
