Answer:
The answer to your question is pH = 6.3
Explanation:
Data
pH = ?
[H⁺] = 4.73 x 10⁻⁷ M
pH is the measure of the concentration of [H⁺]. pH measures the acidity of the solution. If the value of pH is between 0 and 6.9, the solution is an acid. If the pH is 7.0 the solution is neutral and if the pH is between 7.1 and 14, the solution is an alkali.
Formula
pH = -log[H⁺]
Substitution
pH = -log[4.73 x 10⁻⁷]
-Simplification
pH = - (-6.3)
-Result
pH = 6.3
