The solubility products of `AI(OH)_(3)` and `Zn(OH)_(2)` are `8.5xx10^(-23)` and `1.8xx10^(-14)` respectively. If `NH_(4)OH` is added to a solution containing `AI^(3+)` and `Zn^(2+)` ions, then substance precipitated first is:

The solubility products of Al(OH)_(3) and Zn(OH)_(2) are 8.5xx10^(-23) and 1.8xx10^(-14) respectively. If NH_(4)OH is added to a solution containing Al^(3+) and Zn^(2+) ions, then substance precipitated first is:

The solubility products of MA, MB, MC and MD are 1.8xx10^(-10), 4xx10^(-3), 4xx10^(-8) and 6xx10^(-5) respectively. If a 0.01M solution of MX is added dropwise to a mixture containing A^(-), B^(-), C^(-) and D^(-) ions, then the one to be precipitated first will be:
