Answer: 9.88 (approx10)
Explanation:
The pOH of a solution is the negative logarithm of the hydroxide-ion concentration
Answer: pOH = 9.88
Explanation:pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.
[tex]pH=-\log [H^+][/tex]
[tex]pOH=-\log[OH^-][/tex]
Putting in the values:
[tex]pOH=-\log[1.3\times 10^{-10}][/tex]
[tex]pOH=9.88[/tex]
[tex]pH+pOH=9.88[/tex]
[tex]pH=14-9.88=4.12[/tex]
Thus as pH is less than 7 the solution is acidic and pOH is 9.88.
