Question

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

• A. reduced to half
• B. doubled
• C. reduced by 1000 times
• D. increased by 1000 times

Answer 1

Answer: (C)

When $pH=3$ then $\left[H^{+}\right]=10^{-3}M$. After that we increased the $pH$ from $3$ to $6$ then $\left[H^{+}\right]=10^{-6}M$ means reduced $1000$ times.
