Data Given:
[H⁺] = 3.16 × 10⁻⁷ M
To Find:
pH = ?
Solution:
As we know that,
pH = -log [H⁺]
Putting values,
pH = -log (3.16 × 10⁻⁷)
pH = 6.50
Kind of Solution:
As we know, when pH of a solution is equal to 7, it is Neutral. When less than 7, its Acidic and when greater than 7, it is Basic. As this solution has pH 6.50, which is less than 7, so it is slightly Acidic in Nature.
