The concentration of Mg2+ at equilibrium
(25oC) is 0.000144 M. What is the value of
Ksp at this temperature?
In the solubility rules, Mg(OH)2 was listed as an "insoluble" salt. It is actually slightly soluble in an equilibrium reaction: Mg (OH)2 (s) Mg2+ (aq) 20H (aq) The concentration of Mg2+ at equilibrium (25°C) is 0.000144 M. What is the value of Ksp at this temperature? Submit Answer Tries o/99
