Question

What is the pH of a 6.7 x 10^−5 M H+ solution?

Answer 1

Answer:

pH = 4.17

Explanation:

According to the molar concentration you stated, pH of the solution is: 4.17

Remember that pH = - log [H⁺]

and [H⁺] = 10^-pH

When:

pH > 7 →  Basic solution

pH = 7 → Neutral solution

pH < 7 → Acid solution

Answer 2

The answer would be pH of 4.17
