Assuming that Ba ( OH ) 2 is completely ionised in aqueous solution under the given conditions the concentration of H 3 O + ions in 0 . 005 M aqueous solution of Ba ( OH ) 2 at 298   K is _________ × 10 - 12   mol   L - 1 . (Nearest integer)

Correct answer

0

Step-by-step solution

At 298   K : in aq. solution H 3 O + OH - = 10 - 14 H 3 O + = 10 - 14 10 - 2 = 10 - 12
