Question

Pick the statements from the list below that are FALSE.

Answer 1

Answer:

Option A and option D.

Explanation:

A. Kw = [H⁺] [OH⁻] / [H₂O]  FALSE

This is the expression for the water's equilbirium.

2H₂O  ⇄  H₃O⁺  + OH⁻

We can also say: H₂O  ⇄  H⁺  + OH⁻

In the expression for K, we do not consider water.

Option C is correct:  Kw = [H⁺] [OH⁻]

B. True

Kw = Ka . Kb

So, Ka = Kw / Kb

C. We saw, that is true.

D. Ka is not  Kb⁻¹ . FALSE

Ka = Kw / Kb

Ka = 10^⁻(pKa)
