PLEASE HELP QUICK CHEMISTRY! NO LINKS! Solution A has a pH of 2.0. Solution B has a pH of 5.0. Which solution is more acidic? Based on the H+ ion concentrations in the two solutions, how many times more acidic?

If 5.00 mL of 6.00M HCl is added to 95.00 mL of pure water, the final volume of the solution is 100.00 mL. What is the pH of the solution?

Given two solutions, 0.10M HCl and 0.10M HF, which solution has the greater concentration of H+ ions? Calculate pH values for the two solutions, given that [H+] = 7.910-3M in the 0.10M HF.
