pH of $10^{-8} \ M \ HCl$ solution is

$200 \ mL$ of an aqueous solution of $HCl$ $(pH=2)$ is mixed with $300 \ mL$ of aqueous solution of $NaOH$ $(pH=12)$ and is diluted to $1.0 \ L$. The $pH$ of the resulting solution is

The $pH$ of a $0.02 \, M$ solution of hydrochloric acid is

The $pH$ of $10^{-7} \ N \ HCl$ is

The $pH$ value of $0.1 \, M \, HCl$ is approximately $1$. What will be the approximate $pH$ value of $0.05 \, M \, H_2SO_4$?

$NaOH$ is a strong base. What will be the $pH$ of a $5.0 \times 10^{-2} \ M$ $NaOH$ solution? (Given: $\log \ 2 = 0.3$)
