Acids & Bases Introduction
9-4 Naming & Writing Formulas for Acids 19.1-Acid-Base Theories 19.2 Hydrogen Ions and Acidity
2
Properties of Acids Acids are substances that increase the concentration of the H+ ion in an aqueous solution. Acids generally have the form of HA, where A is some anion (Remember polyatomic ions). Example: HCl where A = Cl- Taste sour and tart Corrode metals Electrolytes (conduct electrical current in solution) React with bases to form a salt and water pH is less than 7
