At 100°C, the Kw of water is 5.6x10−13. What is the pOH of a solution that has a pH of 6.25 at 100°C? A) 6.00 B) 6.25 C) 7.00 D) 7.75 E) 8.00

The pOH of a solution that has a pH of 6.25 at 100°C is 7.75 (option D)

Explanation:

pOH + pH = 14

pOH = 14 - 6.25

pOH = 7.75

Therefore, at 100°C, the Kw of water is 5.6x10⁻¹³ and the pOH of a solution that has a pH of 6.25 at 100°C is 7.75.

Thus, option D, is the correct answer.
