Calculate [H3O ], [ClO4–], and [OH–] in an aqueous solution that is 0.130 M in HClO4(aq) at 25 °C.

[H^+]=

[ClO4^-]=

[OH^-]=

Is the solution acidic, basic or neutral?

Expert Solution

We have the chemical reaction

Now Since dissociate 100% then the concentration of ClO₄^- and H⁺ will be equal.

$[ClO_4^-_{(aq)}]=[H^+_{(aq)}]=0.130M$

Here

Here is strong acid , so we can apply

As we know that

By applying this rule we can calculate the , before that we need to calculate the pOH.

Now the concentration of can be determined by:

The concentration of is .

and the solution is acidic .
