In the production of magnesium, Mg(OH)2 is precipitatedby using Ca(OH)2, which itself is “insoluble.” (a) Use Ksp valuesto show that Mg(OH)2 can be precipitated from seawater inwhich [Mg2+] is initially 0.052 M. (b) If the seawater is satu-rated with Ca(OH)2, what fraction of the Mg2+is precipitated?
