In the Group analysis of cations, Ba ²⁺ ~ &~ Ca ²⁺ are precipitated respectively as

Options

  1. Asulphide & sulphide
  2. Bchromate & sulphide
  3. Ccarbonate & carbonate
  4. Dhydroxide & carbonate

Correct answer

C. carbonate & carbonate

Step-by-step solution

In Group V of cation analysis, both Ba²⁺ and Ca²⁺ are precipitated by adding Na₂CO₃ or (NH₄)₂CO₃ solution. Ba²⁺ precipitates as BaCO₃ (white precipitate) and Ca²⁺ precipitates as CaCO₃ (white precipitate). Both form insoluble carbonates under these conditions, making the answer carbonate & carbonate.
