What will be the $\mathrm{H}^{+}$ ion concentration in a solution prepared by mixing $50 \mathrm{~mL}$ of $0.20 \mathrm{M} \mathrm{NaCl}$, $25 \mathrm{~mL}$ of $0.10 \mathrm{M} \mathrm{NaOH}$ and $25 \mathrm{~mL}$ of $0.30 \mathrm{NHCl}$ ?
  1. $0.5 \mathrm{M}$
  2. $0.05 \mathrm{M}$
  3. $0.02 \mathrm{M}$
  4. $0.10 \mathrm{M}$

Solution

$\left[\mathrm{H}^{+}ight]=\frac{(25 \times 0.3-25 \times 0.1)}{100} \mathrm{meq}=0.05 \mathrm{M}$ /
