If pH =3, then [ H +]=10-3 pH =11, then pOH =3 and [ OH- ]=10-3. If equal volumes of two solutions with pH values 3 and 11 are mixed, then pH of resulting solution is 7 because [ H +]of 1 text st solution is equal to [ OH -]of second solution.

If $p H = 3$ , then $[H^{+}] = 1 0^{- 3} & p H = 11$ , then $pO H = 3$ and $[O H^{-}] = 1 0^{- 3}$ . If equal volumes of two solutions with pH values 3 and 11 are mixed, then $p H$ of resulting solution is 7 because $[H^{+}]$ of $1^{st}$ solution is equal to $[O H^{-}]$ of second solution.

If pH=3, then [H+]=10−3&pH=11, then pOH=3 and [OH−]=10−3. If equal volumes of two solutions with pH values 3 and 11 are mixed, then pH of resulting solution is 7 because [H+]of 1st solution is equal to [OH−]of second solution.
