APFIVE Temperature Dependence of Kw
All of the following statements concerning the temperature dependence of $$K_w$$ are true EXCEPT:
A
The value of $$K_w$$ is constant at $$1.0 \times 10^{-14}$$ regardless of temperature.
B
Temperature affects the degree of water autoionization, thereby altering the concentrations of $$[H^+]$$ and $$[OH^-]$$.
C
At temperatures above 25°C, $$K_w$$ increases, which can change the neutral pH value.
D
For example, at higher temperatures, both $$[H^+]$$ and $$[OH^-]$$ concentrations can increase while maintaining $$[H^+][OH^-] = K_w$$.
