Answer:
The pH of the solution is 6.17.
Explanation:
To find the pH of the solution, we have to first calculate its pOH using the formula:
[tex]\boxed{\mathrm{pOH = - log_{10}[OH^-]}}[/tex]
Substituting the given value of [OH⁻] into the formula, we get:
[tex]\mathrm{pOH = -log_{10}(1.49 \times 10^{-8})}[/tex]
[tex]= \bf 7.83[/tex]
Now that we have the value of the pOH of the solution, we can find its pH using the following formula:
[tex]\boxed{\mathrm{pH + pOH = 14}}[/tex]
∴ [tex]\mathrm{pH} + 7.83 = 14[/tex]
⇒ [tex]\mathrm{pH } = 14 - 7.83[/tex]
⇒ [tex]\mathrm{pH } = \bf 6.17[/tex]
