2. If the [H+] in a solution is 2.0 x 10-3M, what is the [OH-] of the solution?
3a. Determine the pH of a solution with a [H+] of 3.0 x 10-8 M? 3b. Is the solution acidic, basic, or neutral?
4. Determine the [H+] of a solution with a pH of 2.35. 4b. Is the solution acidic, basic, or neutral?
5. What is the pH of a solution with an [OH-] of 2.5 x 10-8M? 5b. Is the solution acidic, basic, or neutral?
If [OH-] is 2.50 x 10-11 M, what would the [H+] be for this solution? • Kw = 1.0x10-14 M2= [H+] * [OH-] • Kw = 1.0x10-14 M2= [H+] * [2.50 x 10-11 M] • [H+]= 4.00x10-4 M
If [H+] is 9.50 x 10-5 M, what would the pH be for this solution? • pH= -log [H+] • pH= -log[9.50 x 10-5 M] • pH=4.02 • BONUS: ACIDIC!
If [OH-] is 1.50 x 10-5M, what would the pH be for this solution? • Kw = 1.0x10-14 M2= [H+] * [OH-] • pH= -log [H+] • Kw = 1.0x10-14 M2= [H+] * [1.50 x 10-5 M] • [H+]= 6.67x10-10 M • pH= -log[6.67x10-10 M] = 9.18Basic!
If the pH is 8.90, what would the [H+] be? • 10^-pH= [H+] • 10^-8.90= [H+] • [H+]= 1.25x10-9 M
