In which pair can both substances show basic nature?
Answer and explanation
Correct answer: Soap solution and baking soda solution
The governing concept is that bases produce hydroxide ions in aqueous solution and show alkaline properties. Soap solution is basic because soap undergoes hydrolysis in water, while baking soda solution is mildly basic because sodium bicarbonate reacts with water to produce some hydroxide ions. Vinegar, lemon juice, tamarind, and tomato juice contain acids, so option B is the only pair in which both substances are basic.
