Which substance is likely to taste sour and be acidic in nature?
Answer and explanation
Correct answer: Lemon juice
The governing concept is the common property of acids: many naturally occurring acids have a sour taste, although substances must never be tasted in a laboratory. Lemon juice contains citric acid, so option B is the suitable answer. Soap solution, lime water, and sodium hydroxide solution are basic rather than acidic; their identification should be made with indicators and safe laboratory procedures.
