Hydrogen ion concentration of a solution...

Hydrogen ion concentration of a solution is `2.5xx10^(-4)"mol "dm^(-3)" at "25^(@)C`. Calculate its `OH^(-)` ion concentration.

Text Solution

Verified by Experts

We know that `[H_(3)O^(+)][OH^(-)]=10^(-14)" at "25^(@)C`
`therefore[OH^(-)]=(10^(-4))/([H_(3)O^(+)])=(10^(-14))/(2.5xx10^(-4))=4xx10^(-11)"mol"//dm^(3)`
