Answer:
pOH = 11.7
Explanation:
From the question given above, the following data were obtained:
Concentration of Hydrogen ion [H⁺] = 0.005 M
pOH =.?
Next, we shall determine the pH of the solution. This is illustrated below:
Concentration of Hydrogen ion [H⁺] = 0.005 M
pH =?
pH = – Log [H⁺]
pH = – Log 0.005
pH = 2.3
Finally, we shall determine the pOH of the solution as follow:
pH = 2.3
pOH =.?
pH + pOH = 14
2.3 + pOH = 14
Collect like terms
pOH = 14 – 2.3
pOH = 11.7
Therefore, the pOH of the solution is 11.7
