Question
In a basic solution,A) [OH] [H+] = 14B) the [OH] is equal to the [H+]C) pH = log[OH]D) the [OH] is greater than the [H+]E) the [OH] is less than 1 107 M
Solution
In a basic solution:
A) [OH-] x [H+] = 14 is incorrect. The product of [OH-] and [H+] is equal to Kw, the ion product of water, which is 1.0 x 10^-14 at 25°C, not 14.
B) the [OH-] is equal to the [H+] is incorrect. In a basic solution, the concentration of hydroxide ions [OH-] is greater than the concentration of hydrogen ions [H+].
C) pH = -log[OH-] is incorrect. The pH is calculated as -log[H+], not -log[OH-]. The pOH is calculated as -log[OH-].
D) the [OH-] is greater than the [H+] is correct. In a basic solution, the concentration of hydroxide ions [OH-] is greater than the concentration of hydrogen ions [H+].
E) the [OH-] is less than 1 x 10^-7 M is incorrect. In a basic solution, the concentration of hydroxide ions [OH-] is greater than 1 x 10^-7 M.
