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

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

The basic principle of cotterell precipitator is

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.

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

Most basic hydride of group 15 elements is ..............

Mg is not precipitate in group V because

Mg is not precipitated in V group because:

Which basic radical(s) decolourize acidic KMnO_(4) ?

In qualitative analysis. Explain why The cations of group II are precipitated , in acidic medium while those of group IV in alkaline medium.

A solution containing a group-IV cation gives a precipitate on passing, H_(2)S . A solution of this precipitate in dil. HCl produces a white precipitate with NaOH solution and bluish-white precipitate with basic potassium ferrocyanide. The cation is :
