Write the reaction of `Mg^(2+)` with `Na_(2)`HP`O_(4)` in presence of `NH_(4)` OH and `NH_(4)` CI.

Heating an ammoniacal solution of MgSO_(4) in the presence of NH_(4)Cl and Na_(2)HPO_(4) causes the precipitation of:

MgCO_(3) is not precipitated with the carbonates of Vth group radicals in presence of NH_(4)Cl and NH_(4)OH because:

When NH_(4)Cl is added to a solution of NH_(4)OH :

Assertion: Basic radical of V group are precipitated as their carbonates in presence of NH_(4)OH . Reason: NH_(4)OH maintains the pH of the solution basic.

Which of the following is formed when As_(2)S_(3) is warmed with NH_(4)OH and H_(2)O_(2) ?

Ionisation of NH_(4) OH is supressed by the addition of NH_(4)Cl because

Thermal decomposition of (NH_(4))_(2)Cr_(2)O_(7) involves.

Dissociation of NH_(4)OH is decreased in presence of :-

Statement-1 :Addition of NH_(4)OH to an aqueous solution of BaCl_(2) in presence of NH_(4)Cl (excess) precipitates Ba(OH)_(2) . Statement-2: Ba(OH)_(2) is water soluble.

State why the blue ppt . Formed on addition of NH_(4)OH to CuSO_(4) soln .dissoves to give adeep blue solution with excess of NH_(4)OH . Give an equation for the reaction . State why Zn(OH)_(2) is soluble in excess of NH_(4)OH .
