Answer 2

Explanation:  

1. In an experiment of NaCl with H₂SO₄ , a double displacement reaction takes place with products formed as Na₂SO4 solution and HCl gas.
2. HCl gas when tested with wet blue litmus paper, dissociates to give H⁺ ions indicating the presence of an acid.
3. As a result, the blue litmus paper turns red.
4. We conclude that HCl is an acid.
