16.29 calculate [H+] for each of the following solution and indicate whether the solution is acidic, basic, or neutral.(b) [OH-]= 8.8 * 10-9 M; (c) a solution in which [OH-] is 100 times greater than [H+] SHOW ALL WORK

Expert Solution

b. [OH-]= 8.8 * 10-9 M

Kw = [H^+][OH^-]

[H^+] = Kw/[OH^-]

= 1*10^-14/8.8*10^-9 = 1.136*10^-6M

[H^+] >1*10^-7 It is acidic solution.

b. a solution in which [OH-] is 100 times greater than [H+]

[OH^-] = 100[H^+]

Kw = [H^+][OH^-]

1*10^-14 = [H^+]*100[H^+]

1*10^-14/100 = [H^+][H^+]

[H^+]^2 = 1*10^-16

[H^+] = 1*10^-8 M

[OH^-] = Kw/[H^+]

[OH^-] = 1*10^-14/1.*10^-8

[OH^-] = 1*10^-6M
