Question

calculate the pH and pOH of 0.2 M H2SO4.

Answer 1

pH of any solution can be calculated by using formula -log M (negative log of acid molarity).

So, pH of .01M H2SO4 will be 2.

But remember, this formula is only applicable for strong acids only.

For weak acids, salts of weak acids, acid and its salt, each have its own different equation.
