Answer:

5.18

Explanation:

From the question given above, the following data were obtained:

Concentration of Hydroxide ion [OH¯] = 1.50×10¯⁹ M

pH =?

Next, we shall determine the pOH of the solution. This can be obtained as follow:

Concentration of Hydroxide ion [OH¯] = 1.50×10¯⁹ M

pOH =?

pOH = –Log[OH¯]

pOH = –Log(1.50×10¯⁹)

pOH = 8.82

Finally, we shall determine the pH of the solution. This can be obtained as shown below:

pOH = 8.82

pH =?

pH + pOH = 14

pH + 8.82 = 14

Collect like terms

pH = 14 – 8.82

pH = 5.18

Therefore, the pH of the solution is 5.18
