Answer:
pH = -log(0.4) = 0.398 is the answer
Explanation:
Firstly, we have to use formula for pH and that would be:
pH = -log(H+ concentration)
Where H+ can be the hydrogen or hydronium ion concentration (usually in units of moles/L also called molarity).
To find the H+ concentration of your solution you set up the problem as follows:
(2 mol H+/I mol H2SO4) (0.2 mol H2SO4/I L soln) = 0.4 mol H+/L soln = H+ concentration = 0.4 M
pH = -log(0.4) = 0.398
