The concentration of the hydrogen ion in a sample of soft drink is $$2 \times 10^{-3}\text{ M}$$. The pOH of the solution is ____________ and its $$\text{p}K_w$$ is ________
Correct Answer: 0
PLACEHOLDER ANSWER - the question has two answers. pH $$= -\log(2 \times 10^{-3}) = 3 - 0.301 = 2.699$$. At room temperature $$\text{p}K_w = 14$$, so pOH $$= 14 - 2.699 = 11.301$$.
