Chemistry
1 answer:
loris [4]3 years ago

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
