Answer:
pH = 9.74
The solution is basic
Explanation:
To find the pH of the solution, we need to find the pOH of the solution.
From the question, the concentration of OH^- = 5.5x10^-5 M
pOH = - Log[OH^-]
pOH = - Log 5.5x10^-5
pOH = 4.26
Recall,
pH + pOH = 14
pH = 14 — pOH
pH = 14 — 4.26
pH = 9.74
Since the pH is above 7, the solution is alkaline ie basic
