Worksheet: Autoionization of Water
In this worksheet, we will practice calculating the autoionization constant of water from concentrations of hydronium and hydroxide ions.
Why is a sample of pure water at neutral even though ?
The self-ionization constant of water, , is at .
- AThe concentrations of and ions are exactly equal.
- BWater loses its acidity when heated.
- C molecules cannot be deprotonated.
- DThe concentration of ions is greater than that of ions.
- E is higher at than at .
