Question

Statement 1: Concentrated sulphuric acid reacts with metals and oxidises them.

Statement 2: Concentrated sulphuric acid reacts with non-metals and reduces them.

• A. Statement 1 is true and statement 2 is false.
• B. Statement 1 is true and statement 2 is true.
• C. Statement 1 is false and statement 2 is false.
• D. Statement 1 is false and statement 2 is true.

Answer 1

The correct option is A

Statement 1 is true and statement 2 is false.

Concentrated sulphuric acid reacts with metals and non metals and oxidises them. It is a good oxidizing agent. Sulphuric acid reacts with non-metal such as carbon and metals such as copper to give:

$C+2H_{2}S{O}_4\to C{O}_2+2H_{2}O+2S{O}_2$

$Cu+2H_{2}S{O}_4\to CuS{O}_4+2H_{2}O+2S{O}_2$
