If a substance solution feels soapy and turns red litmus blue, what type is it?

Answer and explanation

Correct answer: Basic

A basic solution can feel slippery or soapy because alkaline substances react with oils on the skin, although an unknown chemical must never be touched directly. The decisive test here is that a base changes red litmus to blue. Therefore, option B is correct. Acids generally turn blue litmus red, neutral solutions show no such characteristic change, and carbonate gas is not a suitable category for a solution displaying this indicator response.
