Home » Water Requirements » Water requirements miscellaneous » Question

If tomato juice is having pH of 4.1, the hydrogen ion concentration will be

1. 10.94 × 10^–5 mol/L
2. 9.94 × 10^–5 mol/L
3. 8.94 × 10^–5 mol/L
4. 7.94 × 10^–5 mol/L

Correct Option: D

pH = – log[H⁺]
4.1 = – log [H⁺]
∴ [H⁺] = 7.94 × 10^-5 mol/L
