NEET Chemistry Functional Group Tests Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Aluminium hydroxide | (i) Yellow precipitate of potassium hexanitritocobaltate (III) |
| (b) Calcium oxalate | (ii) White gelatinous precipitate in lake test |
| (c) Cobalt ion | (iii) White precipitate with ammonium oxalate |
| (d) Strontium ion | (iv) Crimson red flame |
a-ii, b-iii, c-i, d-iv
a-i, b-iv, c-ii, d-iii
a-ii, b-iv, c-iii, d-i
a-iv, b-ii, c-i, d-iii
Correct Answer
Detailed Explanation
Aluminium hydroxide forms a white gelatinous precipitate in the lake test (a-ii), Calcium oxalate gives a white precipitate with ammonium oxalate (b-iii), Cobalt ion produces a yellow precipitate of potassium hexanitritocobaltate (III) (c-i), and Strontium ion confirms with a crimson red flame (d-iv).
