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
