Question

If the pH of vinegar is 3.0, what is the concentration of H+ in vinegar?

Answer 1

Answer: The concentration of
`H^(+)` ions in vinegar is 0.001 M.

Step-by-step explanation:

Given: pH = 3.0

pH is the negative logarithm of concentration of hydrogen ion.

The expression for pH is as follows.

`pH = - log [H^(+)]`

Substitute the value into above expression as follows.

`pH = - log [H^(+)]\\3.0 = - log [H^(+)]\\conc. of H^(+) = antilog (- 3.0)\\= 0.001 M`

Thus, we can conclude that the concentration of
`H^(+)` ions in vinegar is 0.001 M.
