Acids and Bases

Acids, bases, and salts are three classes of compounds that form ions in water solutions.
As a basis for understanding this concept:
a. Students know the observable properties of acids, bases, and salt solutions.
b. Students know acids are hydrogen-ion-donating and bases are hydrogen-ionaccepting
c. Students know strong acids and bases fully dissociate and weak acids and bases
partially dissociate.
d. Students know how to use the pH scale to characterize acid and base solutions.
e.* Students know the Arrhenius, Brønsted-Lowry, and Lewis acid–base definitions.
f.* Students know how to calculate pH from the hydrogen-ion concentration.
g.* Students know buffers stabilize pH in acid–base reactions
