Question

What is the `sf(OH^-)` ion concentration in a solution of 0.0012M strontium hydroxide ?

Answer 1

`[OH^-]=2.4xx10^(-3)"M"`

`Sr(OH)_(2(aq))` contains 2 moles of `OH^(-)` ions so a solution that is `1.2xx10^(-3)"M"` will have an `OH^-` ion concentration which is equal to `1.2xx10^(-3)xx2=2.4xx10^(-3)"M"`.
