In the third group of qualitive analysis, the precipitating reagent is `NH_(4)CI//NH_(4)OH`. The function of `NH_(4)CI` is to

During the precipitation fof third group of qualitative analysis ammonium chloride is added before adding ammonium hydroxide. The function of NH_4CI is to

pH of an aqueous solution of NH_(4)CI is

The qualitative analysis to the salt solution addition of reagents NH_(4)CI+NH_(4)OH and ammonium carbonate give precipitate in precipitate the oxidation state of anion (only magnitude)

Addition of NH_4CI to,NH_4OH results in

Magnesium is not precipitated from a solution of its salt by NH_(4)OH in the presence of NH_(4)CI. Explain.

In qualitative analysis NH_4 Cl is added before NH_4 OH
