The pH of a solution is increased from 3 to 6 ; its H+\mathrm{H}^{+} ion concentration will be

Options

  1. Areduced to half
  2. Bdoubled
  3. Creduced by 1000 times
  4. Dincreased by 1000 times

Correct answer

C. reduced by 1000 times

Step-by-step solution

pH=3…\mathrm{pH}=3 \ldots\left[\mathrm{H}^{+}\right]=10^{-3} ; \quad \mathrm{pH}=6\therefore \left[\mathrm{H}^{+}\right]=10−610^{-6}. Hence \left[\mathrm{H}^{+}\right]isreducedbyis reduced by10^{-3} times.
