When $100 \ mL$ of $0.1 \ M$ $NaOH$ is added to $50 \ mL$ of $0.2 \ M$ $HCl$ at $25 \ ^oC$,the $pH$ of the resulting solution will be:

The highest $pH$ $(14)$ will be of which of the following?

The $pH$ of $0.0001 \ N$ solution of $KOH$ will be

The solubility of $Sr(OH)_2$ at $298 \, K$ is $19.23 \, g/L$ of solution. Calculate the concentrations of strontium and hydroxyl ions and the $pH$ of the solution.

$x \ mg$ of $Mg(OH)_2$ (molar mass $= 58 \ g/mol$) is required to be dissolved in $1.0 \ L$ of water to produce a $pH$ of $10.0$ at $298 \ K$. The value of $x$ is $........... mg$ ($Nearest$ $integer$). ($Given$: $Mg(OH)_2$ is assumed to dissociate completely in $H_2O$)

Which of the following solutions has the highest $pH = 14$?
