Homework Statement
What is the H3O+ concentration with the following scenario
5.3e-2M HCl and 7.70e-2 M NaC2H3O2
Homework Equations
Kw = Kb(Ka) ICE tables
The Attempt at a Solution
Both solutions 100% dissociation
The HCl should be fully neutralized giving 7.70e-2 - 5.3e-2 = 0.024M of the acetate left. Knowing the Kb of acetic acid is 5.56e-10 I set up an ICE table (5.56e-10*0.024)1/2 to find [OH-] to be 0.0000037. Convert that to what H+ concentration by taking 1e-14/0.0000037 = 3e-9. This answer is wrong. Could somebody point out where I went wrong.
