Magnesium hydroxide is only very slightly soluble in water. The reaction by which it goes into solution is: Choose one correct answer.  Why would the solubility of Mg(OH)2 increase upon the addition of in 1 M HCl? a. HCl dissociates into H+ and Cl- ions. Cl- can react with Mg2+, resulting in a forward shift so more Mg(OH)2 is dissolved. b. HCl reacts with Mg(OH)2 allowing it to dissolve better in aqueous solution. c. HCl dissociates into H+ and Cl- ions. H+ can react with the hydroxide ions, resulting in a forward shift so more Mg(OH)2 is dissolved. d. None of these.

Question

Magnesium hydroxide is only very slightly soluble in water. The reaction by which it goes into solution is:

Choose one correct answer. 

Why would the solubility of Mg(OH)2 increase upon the addition of in 1 M HCl?

a. HCl dissociates into H+ and Cl- ions. Cl- can react with Mg2+, resulting in a forward shift so more Mg(OH)2 is dissolved.

b. HCl reacts with Mg(OH)2 allowing it to dissolve better in aqueous solution.

c. HCl dissociates into H+ and Cl- ions. H+ can react with the hydroxide ions, resulting in a forward shift so more Mg(OH)2 is dissolved.

d. None of these.
