Answer:
- [H₃O⁺] = 0.032 M
Explanation:
The acidity of a solution is measured by its pH, which is the logarithm of the inverse of the molar concentration of hydronium (H₃O⁺) ions:
- pH = log 1 / [H₃O⁺] = - log [H₃O⁺]
When you know the pH value you can find hydronium concentration using the antilogaritm function:
The unit of molar concentration is M.
To prove your answer you can take the logarithm of 0.0316:
- log (0.0032) ≈ 2.500
