Answer:
5.7
Explanation:
The pH can be calculated by:
pH = -log[H⁺]
Where [H⁺] is the concentration of hydrogen ions. The pH is a way to identify if the solution is an acid or a base. When pH is equal to 7, the solution is neutral, when it is less than 7, it is acid, and when it is larger than 7, it's a base.
So, for the acid solution given, [H⁺] = 2.0x10⁻⁶ M
pH = -log(2.0x10⁻⁶)
pH = 5.7
