Solution
The correct option is A Car battery acid < Apple juice < Water < Baking soda < Bleach The order of pH values is- Strong acids < Weak acids < Neutral substances (pH 7) < Weak bases < Strong bases
1. Car battery acid contains hydrochloric acid which is a strong acid 2. Apple juice contains malic acid which is a weak acid. 3. Water is neutral 4. Baking soda contains sodium bicarbonate which is a weak base 5. Bleach contains sodium hydroxide which is a strong base
Hence, the correct order of pH is Car battery acid < Apple juice < Water < Baking soda < Bleach
