Assuming that

Ba ( OH{)}_{2}

is completely ionised in aqueous solution under the given conditions the concentration of

{H}_{3}{O}^{+}

ions in

0 . 005M

aqueous solution of

Ba ( OH{)}_{2}

298K

is _________

\times {10}^{- 12}mol{L}^{- 1} .

(Nearest integer) Assuming that Ba ( OH ) _ 2 is completely ionised in aqueous solution under the given conditions the concentration of H

Correct answer

Step-by-step solution

Assuming that Ba ( OH ) _ 2 is completely ionised in aqueous solution under the given conditions the concentration of H

At $298K$ : in aq. solution \left[{H}_{3}{O}^{+}\right]\left[{OH}^{-}\right] = {10}^{- 14} $</p><p>\left[{H}_{3}{O}^{+}\right] = \dfrac{{10}^{- 14}}{{10}^{- 2}} = {10}^{- 12}$
