The pH of a solution is increased from 3 to 6 ; its 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 [ H ⁺ ]=10⁻³ ; pH =6 [ H ⁺ ]=10⁻⁶ . Hence [ H ⁺ ] is reduced by 10⁻³ times.
