Explanation / Answer

PART A) most numbers are not clear

acidic --> [H+] > 10^-7 or [OH-] < 10^-7

basic --> [H+] < 10^-7 or [OH-] > 10^-7

neutral, [H+] = 10^-7 or [OH-] = 10^-7

B)

if

[H3O+] = 7.6*10^-5 M

find [OH-]

Kw = [H3O+][OH-]

10^-14 = (7.6*10^-5)*[OH-]

[OH-] = (10^-14) / (7.6*10^-5) = 1.3157*10^-10, this is acidic

C)

[OH-] = 1.5*10^-2

[H3O+] = (10^-14)/(1.5*10^-2) = 6.6666*10^-13 M
