Water, H2O(l), can form both the hydronium ion,
H+, and the hydroxide ion, OH− when it
undergoes autoionization:
The ion product of water, Kw is the equilibrium
constant for the autoionization reaction:
Which one of the following statements
is false when describing this
reaction?
Group of answer choices
A. The concentrations of hydronium ions and hydroxide ions at
25°C always multiply to equal 1.0 x 10-14 at
equilibrium.
B. The concentrations of hydronium ions and hydroxide ions
behave inversely proportional to teach other – at equilibrium as
one increases the other decreases.
C. The concentrations of hydronium ions and hydroxide ions at
25°C are always equal.
D. The pKw always calculates to equal 14 at
25°C.
