3.) One liter of an aqueous solution contains 6.02 x 1021H3O+ions. What is the [H3O+] of the solutioninmol/L?
1.) Sherlock Holmes is restoring an art artifact. He proceeded by diluting nitric acid to 1.8 M, 0.25 M, and 0.0058 M. Calculate the hydronium ion concentration, pH, hydroxide ion concentration, and pOH of the 3 solutions.
2.) Sheldon Cooper, a researcher, obtained a solution with [H3O+] = 2.3 x 10-4 M at 25oC after mixing HCl (g) with pure H2O. Determine the concentration of the hydroxide ions. Is the solution neutral, acidic, or basic?
3.) One liter of an aqueous solution contains 6.02 x 1021H3O+ions. What is the [H3O+] of the solutioninmol/L?
4.) Calculate the [H+] in 8.8 x 10-4 MCa(OH)2.
5.) What is the [OH-] of a 2.5 x 10-3M Ba(OH)2 solution?
6.) Determine the pH of a KOH solution made from 0.251 g KOH and enough water to make 1.00 x 102 mL solution.
7.) What is the pOH of a solution in which [H+]= (5.0)[OH-]?
8.) Find the [H+]and pH of a tap water sample in which [OH-]is 2.0 x 10-7
