In group III, the basic radicals are precipitated as their.......

Group IV basic radicals are precipitated as.........from .........medium.

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.

The basic principle of cotterell precipitator is

In qualitative analysis of group I radicals, a white precipitate is formed which is insoluble in boiling water but when treated with NH_4 OH it turns black. The precipitate may be

A metal carbonate, on being heated strongly gives a solid that forms a greenn solid with CoO. In which analytical group will the cation be precipitate and what will be the colour of the precipitate ?

H_(2)S is passed through the solution in an acididc medium to precipitate the sulphides of group II cations, but in an alkaline medium to precipitate the sulphides of group IV cations because:

Which radical of group IV^(th) gives bluish white / white precipitate with excess K_(4)[Fe(CN)_(6)] ?

Select the basic and acidic radicals in the MgSO_4 .

Select the basic and acidic radicals in the ZnCO_3 .

Why are the group IV cations not precipitated as sulphides on passing H_(2)S gas through group II solution?
