Match the following
a Haematite i \(HgS\) b Cinnabar ii \(Fe_3O_4\) c Hornsilver iii \(Fe_2O_3\) d Magnetite iv \(AgCl\)
| a | Haematite | i | \(HgS\) |
| b | Cinnabar | ii | \(Fe_3O_4\) |
| c | Hornsilver | iii | \(Fe_2O_3\) |
| d | Magnetite | iv | \(AgCl\) |
- a-iii, b-iv, c-i, d-ii
- a-iii, b-i, c-iv, d-ii
- a-ii, b-iv, c-i, d-iii
- a-ii, b-i, c-iv, d-iii
The Correct Option is B
Solution and Explanation
Haematite is an ore of iron with the chemical formula Fe₂O₃ → matches (iii)
Cinnabar is the main ore of mercury, chemical formula HgS → matches (i)
Hornsilver is another name for silver chloride → matches (iv)
Magnetite is an iron ore with formula Fe₃O₄ → matches (ii)
The correct option is (B): a-iii, b-i, c-iv, d-ii

- Alex was given a solution of an unknown salt Y for analysis. He performed the following tests and recorded his observations:
• To a part of the solution Y, he added silver nitrate solution and obtained a white precipitate which was soluble in ammonium hydroxide solution.
• To the remaining solution he added a few drops of sodium hydroxide solution and obtained a pale blue precipitate.
Based on the observations made by Alex, identify:
(a) the anion and
(b) the cation present in salt Y.
