`Fe(OH)_(3)` when treated with `FeCl_(3)` solution gives a reddish–brown solution. The process involved is:

FeCl_(3) solution is acidic due to hydrolysis of :-

The sodium extract of an organic compound on treatment with FeSO_(4) solution, FeCl_(3) and HCl gives red solution. The red colour of

A certain compound (X) when treated with copper sulphate solution yields a brown precipitate. On adding hypo solution the precipitate turns white. The compound is

(i)A black coloured compound (B) is formed on passing H_(2)S through the solution of a compound (A) in NH_(4)OH (ii) (B) on treatment with HCl and potassium chlorate or aquaregia gives (A) (iii) (A) on treatment with KCN gives a buff/reddish-brown coloured precipitate which dissolves in excess of this reagent forming a compound ( C) . (iv)The compound ( C) is changed into a compound (D) when its aqueous solution is boiled in air. (v)The solution of (A) was treated with excess of NaHCO_(3) & then with bromine water. On cooling & shaking for some time, a green colour of compound (E) is formed.No change is observed on heating. Identify (A) to (E) and give chemical equations.

What happens when C Cl_(4) is treated with AgNO_(3) solution ?

A freshly prepared Fe(OH)_(3) precipitate is peptized by adding FeCl_(3) solution. The charge on the colloidal particle is due to preferential adsorption of
