If the following chemical species are individually added to a saturated solution of Mg(OH)2, determination what each of their impact will be on the solubility of this Group II salt. (will it increase decrease of=r not change)
HClO4 is added to the solution. |
|
CsI is added to the solution. |
|
MgCl2 is added to the solution. |
So, the solubility of Mg(OH)2 will increase on addition of CsI.
c) Addition of MgCl2
MgCl2 will furnish Mg2+ ions in solution. This being common ion will drag equilibrium to left, thereby decreasing the solubility of Mg(OH)2.
