NEET Chemistry Functional Group Tests Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Cobalt ion test | (i) Yellow precipitate of barium chromate |
| (b) Calcium ion test | (ii) White precipitate of calcium oxalate |
| (c) Barium ion test | (iii) Yellow precipitate of potassium hexanitritocobaltate(III) |
| (d) Magnesium ion test | (iv) No precipitate formed with ammonium oxalate |
a-iii, b-ii, c-i, d-iv
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iii, d-iv
a-iv, b-i, c-ii, d-iii
Correct Answer
Detailed Explanation
The cobalt ion test produces a yellow precipitate of potassium hexanitritocobaltate(III), the calcium ion test gives a white precipitate of calcium oxalate, while the barium ion test results in a yellow precipitate of barium chromate. The magnesium ion test typically does not produce a precipitate with ammonium oxalate.
