Properties of Acids and Bases

Acids

Acids taste sour, will change the color of an acid-base indicator, and can be strong or weak electrolytes in aqueous solution.

Properties of Acids and Bases

Bases

Bases taste bitter, feel slippery, will change the color of an acid-base indicator, and can be strong or weak electrolytes in aqueous solution.

19.1 Acids and Bases

Hydrochloric Acid

Acids and Bases

Acids

• Acids that contain one ionizable hydrogen, such as nitric acid (HNO3), are called monoprotic acids.

• Acids that contain two ionizable hydrogens, such as sulfuric acid (H2SO4), are called diprotic acids.

• Acids that contain three ionizable hydrogens, such as phosphoric acid (H3PO4) are called triprotic acids.

Acid-Base Reactions

a. In general, the reaction of an acid with a base produces water and one of a class of compounds called salts.

Acid-Base Reactions

a. Reactions in which an acid and a base react in an aqueous solution to produce a salt and water are generally called neutralization reactions.
