Calculate the pH of a sample of acid rain that has the H30t concentration of 3.0x4-5m
To calculate the pH of a sample of acid rain with a given H3O+ concentration, you can use the formula:
pH = -log[H3O+]
Given that the H3O+ concentration is 3.0x10^-5 M, let's plug this value into the formula:
pH = -log(3.0x10^-5)
To evaluate this expression, you need to take the negative logarithm (base 10) of the H3O+ concentration.
pH = -log(3.0x10^-5)
= -(-4.52) (using a calculator)
= 4.52
Therefore, the pH of the acid rain sample with the given H3O+ concentration is approximately 4.52.
