The hydronium ion concentration of a solution increases. Select all of the following that will occur as a res The solution will become more acidic The solution will become more basic The pOH will go up The solution will attain a neutral pH The pH will go down The 0000 hydroxide ion concentration will decrease The numerical value of [H3O*] will increase The pH will go up The value of Kw will go down The value of Kw will go up

If the pH of a solution is 4.5, what is the [H3O+] of the solution? Hint [H3O+] = 10-PH 90.0 M 3.16x104 M 3.16x10-5 M 0.65 M 1.50 M
