Question

describe identification procedure of Ba2+ or Ca2+ radical from given unknown solution

Answer 1

Identification of procedure of Ba₂⁺ and Ca₂⁺ From given unknown Solution.

Step -1 .

We have to Treat the mixture with 'NH₄Cl + NH₄OH '  and (NH₄)₂ CO₃ .

Step - 2

We have to take two part of the mixture and now dissolve it in CH₃COOH (acetic acid)

Step - 3

We have to Treat one part with Potassium chromate (K₂CrO₄) solution  and other part with Ammonium oxalate solution (NH₄)₂C₂O₄

Result :- So we can observe that The chromate part  will give us a Yellow precipitate for Barium and on the other hand the Oxalate part one will give us a White test tube for Calcium .

Hope it Helps :-)
