Answer:
10.7
Explanation:
According to this question, we have 4.60 × 10^-4 M hydroxide ion (OH-) concentration.
Since we were given the OH concentration, we first calculate the pOH of the solution, which is given as:
pOH = -log {OH-}
pOH = - log {4.60 × 10^-4}
pOH = - log {0.000460}
pOH = 3.337
pOH = 3.34
Given that; pOH + pH = 14
The pH of the solution = 14 - pOH
pH = 14 - 3.34
pH = 10.66
pH = 10.7
