What does the value of $\mathrm { K } _ { \mathrm { W } }$ say about the extent to which water molecule react with themselves?
A)Because the value of $\mathrm { K } _ { \mathrm { W } }$ is so small,the extent to which water ionizes is quite large.
B)Because the value of $\mathrm { K } _ { \mathrm { W } }$ is so small,the extent to which water ionizes is quite small.
C)Water molecules react with themselves at a constant rate,never increasing or decreasing.
D)When an acid is added to water,the value of $\mathrm { K } _ { \mathrm { W } }$

The value of $\mathrm{K}_\mathrm{W}$ (the ion product constant for water) is $1.0 \times 10^{-14}$ at 25°C, indicating that the extent to which water ionizes is quite small. This small value shows that only a tiny fraction of the water molecules dissociate into hydrogen ions ($H^+$) and hydroxide ions ($OH^-$) under standard conditions.
