(Dithizone by itself is environmentally friendly in colour plus the lead dithizone shaped is violet in colour. Therefore, The online resultant colour of the answer becomes crimson).
• Deeply coloured material like KMnO4 should be decolourised with Liquor and filtrate is utilized for normal limit test
The limit test of lead is based about the reaction involving lead and diphenyl thiocarbazone (dithizone) within an alkaline Resolution to form a lead dithionate elaborate ensuing producing a red coloration. later on this crimson colour shall be in contrast with that in the regular.
