Which type of substance generally feels soapy to touch?
Answer and explanation
Correct answer: Base
The governing concept is the characteristic nature of acids and bases. Aqueous bases generally feel slippery or soapy because they react with oils on the skin; soap solutions are commonly alkaline. Therefore, option B, base, is correct. Acids are usually associated with sourness and can be corrosive, salts do not generally have a soapy feel, and metals are solids with metallic properties. Chemicals must never be identified by touching them in a laboratory.
