Base pH > 7 [H+] < [OH-]
Acid pH < 7 [H+] > [OH-]
Neutral pH = 7 [H+] = [OH-]
pH + pOH = 14
A decrease of 1 pH unit represents a tenfold increase in the hydronium ion concentration
An increase of 1 pH unit represents a tenfold increase in the hydroxide ion concentration
The Arrhenius Definition
Acid: a substance that when dissolved in water increases the concentration of hydrogen ion, H+
Base: a substance that when added to water increases the concentration of hydroxide ion, OH-
ACIDS AND BASES ARE ELECTROLYTES
An electrolyte is a substance that, when dissolved in water, forms a solution capable of conducting an electric current
Neutralization Reaction
Acid + Base --> Salt + Water
Acids react with metals to form H2 gas
Be familiar with the common acids and bases found on Table L & K
Use Table M to determine what color acids and bases turn indicators
Bronsted-Lowry Theory of Acids and Bases
Acid- proton (H+) donor
Base- proton (H+) acceptor
Titration: A laboratory procedure in which a volume of solution of known concentration is used to determine the concentration of another solution
