In a solution at 25°c, the [h+] is 3.5 × 10−6 m. what is the [oh−]?

[OH-] = 2.857 x 10∧-9

Explanation:

At 25 °C; the product of [H+] and [OH-] is 10∧-14

[H+] [OH-] = 10∧-14

and [H+] = 3.5 x 10∧-6

[OH-] = 10∧-14 / (3.5 x 10∧-6) = 2.857 x 10∧-9.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
