In this paragraph, it is given that due to high solubility product of Mg(OH)2 as compared to that of MgCO3 that Mg(OH)2 is precipitated ?
Dear Student,
Greater the solubility product, greater is the tendency to precipitate out in solution.
Since, solubility product of Mg(OH)2 is greater than MgCO3, therefore, Mg(OH)2 precipitates out first and then MgCO3 will precipitate.
