Answer: [tex][H_3O^+]=1.6\times 10^{-10}M[/tex] , the solution is basic
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.
[tex]pH=-\log [H_3O^+][/tex]
[tex]pOH=-\log[OH^-][/tex]
Putting in the values:
[tex]pOH=-\log[5.5\times 10^{-5}][/tex]
[tex]pOH=4.2[/tex]
[tex]pH+pOH=14[/tex]
[tex]pH=(14-pOH)=(14-4.2)=9.8[/tex]
[tex]9.8=-\log [H_3O^+][/tex]
[tex][H_3O^+]=1.6\times 10^{-10}M[/tex]
As pH is more than 7, the solution is basic
