Question

Consider the graphs shown below which show how Mg(OH)₂ behaves under different conditions. The y-axis in each graph represents the solubility of Mg(OH)₂ and the x-axis represents the concentration of another reagent. Identify the graph that corresponds to the solubility of Mg(OH)₂ as HCl is added to the solution.

Graph A shows the solubility of Mg(OH)2 as HCl is added, increasing with concentration.

Accepted Answer

Graph B depicts the solubility of Mg(OH)2 decreasing as HCl concentration increases.

Answer

Graph C illustrates a constant solubility of Mg(OH)2 regardless of HCl concentration.

Answer

Graph D shows the solubility of Mg(OH)2 remaining unchanged with increasing HCl concentration.
