Question

Which solution has a greater concentration of hydrogen ions (H), a solution with a pH of 3 or one with a pH of 7?

Answer 1

`pH=3`

Explanation:

By the definition of `pH`, it is the potential of hydrogen. It is given by the equation,

`pH=-log[H^+]`

That means, per `1` unit of lower `pH`, there will be `10` times more hydrogen ions `(H^+)` than the level above.

`3<7`

`:. pH = 3 > pH = 7` in terms of `(H^+)` ions.
