The traditional definition of acids is based on the observations of |
Arrhenius |
|

hydrogen and ionizes to form hydrogen ions |
|
What is the basic assumption in the Arrhenius theory |
Because acids and bases conduct electric current, they must produce ions in solution |

They increase the concentration of hydroxide ions in aqueous solution |
|
Which statement about Arrhenius bases is FALSE |
They increase the concentration of hydrogen ions in aqueous solution |
