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)
Alex_Xolod [135]

Answer:

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.

What two pieces of evidence did van Helmont use to reach his conclusion
Sav [38]

Explanation:

He weighed silver, dissolved it in acid, and then recovered all the original silver by reacting the solution with copper. He also showed, by using iron to recover the copper, that this displacement of one metal from its salt by using a second metal was not because of transmutation, as many had held.
