turns blue litmus paper red

turns red litmus paper blue

does not affect litmus paper

bleaches litmus paper

Answer Details

Dry hydrogen chloride gas (HCl) when dissolved in methylbenzene does not affect litmus paper. This is because methylbenzene is a non-polar solvent and does not contain water, which is required for litmus paper to change color. Therefore, litmus paper cannot be used to test the acidity or basicity of the solution.
