Answer:
6.59.
Explanation:
∵ pOH = - log[OH⁻]
∴ pOH = - log[OH⁻] = - log(3.9 x 10⁻⁸) = 7.408.
∵ pH + pOH = 14.0.
∴ pH = 14.0 - pOH = 14.0 - 7.408 = 6.59.
Answer:
The pH of the solution is 6.58.
Explanation:
The pOH of the solution is defined as negative logarithm of hydroxide ion concentration.
[tex]pOH=-\log[OH^-][/tex]
The concentration of hydroxide ions = [tex][OH^-]=3.8\times 10^{-8}M[/tex]
[tex]pOH=-\log[3.8\times 10^{-8}M]=7.42[/tex]
pH + pOH = 14
pH = 14- 7.42 = 6.68
The pH of the solution is 6.58.
