Name a metallic hydroxide which gets precipitated by `NH_(4)OH` even in the presence of `NH_(4)Cl`.

Name a metallic hydroxide which does not get precipitated by NH_(4)OH io the presence of NH_(4)Cl .

Which of the following is not precipitate by H_(2)S in presence of NH_(3)

Name : a metallic hydroxide soluble in excess of NH_( 4)OH .

Name a metallic hydroxide that is insoluble in NH_(4)OH but dissolves readily in solution of NH_(4)CI .

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

Reduction of nitrobenzene in the presence of Zn//NH_(4)Cl gives

An aqueous solution of colourless metal sulphate M , gives a white precipitate with NH_(4)OH .This was soluble in excess of NH_(4)OH . On passing H_(2)S through this solution a white precipitate is formed.The metal M in the salt 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.

A solution when diluted with H_(2)O And boiled gives a white precipitate .On the addition of excess NH_(4)Cl & NH_(4)OH the volume of the precipitate decreases leaving behind a white gelationtious precipitate identify the precipitate which dissolves in NH_(4)OH//NH_(4)Cl :

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