Title: Acids and bases calculations
Post by: Haztik on October 11, 2020, 02:54:52 AM

I have two questions in my homework that I’m unable to solve.
Are they solvable? If so how?
4) The pH of a H2SO4 solution is 2. What is the initial concentration of H2SO4 ? Ka2 = 0.01
6) What is the S2- concentration of a 10-3 M HCl solution which is saturated with H2S ?
H2S(aq) + 2H2O(l) 2H3O+(aq) + S2-(aq) Ka = 1.1 × 10-21

You have to show your attempts at solving the problem to receive help, this is a forum policy.

Yes, they can be both solved.
