Question

What is the relationship between the pH of water, vinegar, and ammonia?

Answer 1

Well, since they are ALL aqueous solutions, their ion product, `[HO^-][H_3O^+]` `=` `10^(-14)` under standard conditions.

Explanation:

And taking negative `-log_10` of both sides, we would find that,

`pOH+pH=14`.

For water `pOH=pH=7`. For vinegar, a weak acid, `pH~=2.2`. For ammonia, a weak base, `pH~=11.5`.

What are `pOH` for vinegar, and ammonia?
