4. Calculate the pH of a 1.5 x 10-7 M solution of Sr(OH)2, a strong base.
Which of the following is an appropriate condition for determining whether the dissociation of water significantly affects the pH of a basic solution? The dissociation of water affects the pH if:
a) the [H+] from the base dissociation alone ([H+]b) is greater than 1.0x10-7 M
b) [H+]b is less than 1.0x10-6 M
c) [OH-]b is greater than 1.0x10-6 M
d) [OH-]b is less than 1.0x10-6 M
