Chemistry · EQUILIBRIUM
हिन्दीThe \( \text{pH} \) of a solution is decreased from \( 5.0 \) to \( 2.0 \). By what factor has the concentration of \( \text{H}^+ \) ions increased?
Correct answer · Option 4
\( 1000 \)
Explanation
\( [\text{H}^+]_1 = 10^{-5}\text{ M} \) and \( [\text{H}^+]_2 = 10^{-2}\text{ M} \). The ratio is \( \frac{10^{-2}}{10^{-5}} = 10^3 = 1000 \).
