Term
| acid (designated as "HA") |
|
Definition
| a substance that produces H3O+ in water by adding an H+ to H2O [HA + H2O <--> A– + H3O+]
also donates an H+ to a base |
|
|
Term
|
Definition
| a substance that produces OH– in water by accepting an H+ from H2O [B + H2O BH+ + OH–]
also accepts an H+ from an acid [B + HA <--> BH+ + A–] |
|
|
Term
|
Definition
| the B and BH+ and the HA and A– |
|
|
Term
|
Definition
| when an acid and a base react to produce water |
|
|
Term
|
Definition
| the reaction between two water molecules:
2 H2O <--> H3O+ + OH–
has an equilibrium constant Kw = [H3O+][OH–] = 10–14 |
