The function of `Fe(OH)_3` in the contact process is

In the formation of SO_(3) by contact process, the conditions used are

In the formation of SO_(3) by contact process, the conditions used are

Assertion : A colloidal sol. Of Fe(OH)_(3) formed by peptisation carries positive charge. Reason : During formation of Fe(OH)_(3), the electrons are lost by the particles.

A colloidal solution of Fe(OH)_(3) in water is :-

If the concentration of OH^(-) ions in the reaction Fe(OH)_(3)(s)hArr Fe^(3+)(aq)+3OH^(-)(aq) is decreased by 1/4 times, then equilibrium concentration of Fe^(3+) will increase by
