Question

Mercury + sulphuric acid $\to$ No reaction. This is because:

• A. Mercury is a liquid.
• B. Sulphuric acid is a weak acid.
• C. Mercury is above hydrogen in reactivity series.
• D. Mercury is below hydrogen in reactivity series.

Answer 1

The correct option is D

Mercury is below hydrogen in reactivity series.

Mercury is less reactive than hydrogen. Hence, it is placed below hydrogen in the reactivity series. Mercury does not react with sulphuric acid because it can't displace hydrogen form the acid.
