Asolution is considered basic or alkaline if its ph is 7.
a. equal to
b. less than
c. greater than

false

because it does not have the potential to be entirely used up

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
