Question

6 of 15 The solubility of MgCO3 (Ksp-3.5x10) increases with which of the following? O raising the pH (Ksp of Mg(OH)2=1.8x10-11) O adding MgSO4 O adding CaCl2 (Ksp of CaCO3 4.5x10) O removing water 7 of 15 To determine experimentally the Ksp of a salt, all the following could work except Oadd distilled water to a massed salt sample until it dissolves completely Ouse a magnetic stirring rod and measure the rate at which a pre-massed sample of salt dissolves in a measured volume of distilled water Oslowly add salt from a measured mass to a measured volume of distilled water until it no longer dissolves Oadd measured masses of distilled water and salt, and filter out the undissolved salt
