A solution is made by mixing exactly 500 mL of 0.178 M NaOH with exactly 500 mL of 0.100 M CH3COOH. Calculate the equilibrium concentrations of H+, CH3COOH, CH3COO-, OH-, and Na+.

A 10.0-mL solution of 0.30 M NH3 is titrated with a 0.100 M HCl solution. Calculate the pH after the following additions of the HCl solution: a) 0.00 mL b) 10.0 mL c) 30.0 mL d) 40.0 mL

Angle of refractions! I need help finding angle of incidence in air(or water or glass) it is for one of my labs. It iOS in a data table though.

I calculated all of them and this is what I got: 1) [H+] = 2.56x10^-13 M 2) [OH-] = .039 M 3) [Na+] .089 M 4) [CH3COO-] = .05 5) [CH3COOH] = 0 All of them were right except number 5 and I don't know what the answer to number 5 is suppose to be.

yes 7.11E-10 was the right answer thank you very much for the help :)

I don't even know where to start. There is no volume for HCl and am not sure how the equation is suppose to look like. I'm just confused about this problem.

Thank you for the help
