If an aqueous solution has a hydroxyl ion concentration of 1 × 10 − 6 M, what is the concentration of hydrogen ion ( [ H + ] ) ?

Respuesta :

Answer : The concentration of [tex]H^+[/tex] ion is, [tex]1\times 10^{-8}M[/tex]

Explanation : Given,

Concentration of [tex]OH^-[/tex] ion = [tex]1\times 10^{-6}M[/tex]

First we have to calculate the pOH.

[tex]pOH=-\log [OH^-][/tex]

[tex]pOH=-\log (1\times 10^{-6})[/tex]

[tex]pOH=6[/tex]

Now we have to calculate the pH.

[tex]pH+pOH=14\\\\pH=14-pOH\\\\pH=14-6\\\\pH=8[/tex]

First we have to calculate the concentration of [tex]H^+[/tex] ion.

[tex]pH=-\log [H^+][/tex]

[tex]8=-\log [H^+][/tex]

[tex][H^+]=1\times 10^{-8}M[/tex]

Thus, the concentration of [tex]H^+[/tex] ion is, [tex]1\times 10^{-8}M[/tex]
