Answer #1

1.
pH = 9.09
pOH = 14 - pH = 14 - 9.09 = 4.91
[H+] = 10^(-pH) = 10^(-9.09) = 8.13*10^-10 M
[OH-] = 10^(-pOH) = 10^(-4.91) = 1.23*10^-5 M

Basic since [OH-]>[H+]

2.
pOH = 3.92
pH = 14 -pOH = 14 - 3.92 =10.08
[H+] = 10^(-10.08) = 8.32*10^-11 M
[OH-] = 10^(-3.92) = 1.2*10^-4 M
Basic since [OH-]>[H+]

3.
[H+] = 8.8*10^-11 M
[OH-] = 10^-14/ [H+] = 10^-14 /(8.8*10^-11) = 1.14*10^-4 M

pH = - log [H+] = -log (8.8*10^-11 )= 10.06
pOH = 14 - pH = 14 - 10.06 = 3.94
Basic since [OH-]>[H+]

4.
[OH-] = 8.5*10^-2 M
[H+] = 10^-14/ [OH-] = 10^-14 /(8.5*10^-2) = 1.18*10^-13 M

pH = - log [H+] = -log (1.18*10^-13 )= 12.93
pOH = 14 - pH = 14 - 12.93 = 1.07
Basic since [OH-]>[H+]
