How many millimoles of `MgCI_(2)` should be added to just precipitate `Mg(OH)` in 500 ml buffer solution containing `0.1 M NH_(4)OH` and `0.1M(NH_(4))
How many millimoles of `MgCI_(2)` should be added to just precipitate `Mg(OH)` in 500 ml buffer solution containing `0.1 M NH_(4)OH` and `0.1M(NH_(4))_(2)SO_(4)`? {Given : `K_(b) (NH_(4)OH) = 10^(-5), K_(sp) [Mg(OH)_(2)] = 10^(-11)}`
