$600 \mathrm{~mL}$ of $0.01~\mathrm{M} ~\mathrm{HCl}$ is mixed with $400 \mathrm{~mL}$ of $0.01~\mathrm{M} ~\mathrm{H}_{2} \mathrm{SO}_{4}$. The $\mathrm{pH}$ of the mixture is ___________ $\times 10^{-2}$. (Nearest integer)
[Given $\log 2=0.30$
$\log 3=0.48$
$\log 5=0.69$
$\log 7=0.84$
$\log 11=1.04]$
Answer (integer)
186
Solution
<p>$\mathrm{[H^+]=\frac{6+8}{1000}=14\times10^{-3}}$</p>
<p>$\mathrm{pH=3-\log14}$</p>
<p>$=3-.3-.84$</p>
<p>$=1.86=186\times10^{-2}$</p>
