NEET Chemistry (general) Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Charcoal cavity test (i) White precipitate of zinc hydroxide (b) Zinc confirmation test (ii) White crystalline precipitate of magnesium ammonium phosphate (c) Magnesium confirmation test (iii) Coloured residue from metallic carbonate (d) Bromide ion test (iv) Orange brown color in organic layer
Choose the correct matching:
a-iii, b-i, c-ii, d-iv
a-ii, b-iii, c-i, d-iv
a-iii, b-ii, c-i, d-iv
a-ii, b-i, c-iv, d-iii
Correct Answer
Detailed Explanation
The charcoal cavity test results in a coloured residue from the decomposition of metallic carbonate. The zinc confirmation test produces a white precipitate of zinc hydroxide. The magnesium confirmation test yields a white crystalline precipitate of magnesium ammonium phosphate. The bromide ion test shows an orange brown color in the organic layer due to bromine dissolution.
