Question

Why is it necessary to remove interfering radicals from group 3 analysis

Answer 1

Ello user !!!!!!!!!!!!

Here is your answer,

====================================================

Interfering radicals are oxalate, tartrate, fluoride, borate and phosphate and they are anionic radicals.

They form complex with IIIrd gr group reagent ammonium chloride and ammonium hydroxide.

This leads to incomplete precipitation of IIIrd group cations and causes immature precipitation of IVth and Vth group cations in alkaline medium.

HOPE THIS HELPS YOUU :)
