a. Will a precipitate of`Mg(OH)_(2)` be formed in a `0.001M` solution of `Mg(NO_(3))_(2)` if the `pH` of solution is adjusted to `9.K_(sp)` of `Mg(OH)_(2) = 8.9 xx 10^(-12)`.  b. Calculate `pH` at which `Mg(OH)_(2)` begin to precipitae form a solution containing `0.1M Mg^(2+)` ions. `K_(sp) of Mg(OH)_(2) =1 xx 10^(-11)`.  c. Calculate `[overset(Theta)OH]` of a solution after `100mL` of `0.1M MgC1_(2)` is added to `100mL` of `0.2M NaOH. K_(sp) Mg(OH)_(2) = 1.2 xx 10^(-11)`.
