Chemistry - Ionic Equilibrium Question with Solution | TestHub

If two solutions of same$\text{pH}$are mixed, no change in$\text{pH}$is observed.$\text{pH}$of water will be$\text{7,}$that of$\text{100}\text{cc}$of$\text{0}\text{.1}\text{M}\text{HCl}$and$\text{1}\text{cc}$of$\text{0}\text{.1}\text{M}\text{HCl}$will be$\text{1}$(as${\text{H}}^{\text{+}}$concentration is$\text{0}\text{.1}$)
$\text{0}\text{.01}\text{N}\text{HCl}$has also$\mathrm{p}\mathrm{H}=2$.
So adding this to a$1000\mathrm{ }\mathrm{c}\mathrm{c}$solution of$\text{pH}\text{2}$will not make any difference in$\mathrm{p}\mathrm{H}$
