Acids & Bases Vocab.

World of Chemistry (Zumdahl) Chapter 16

Conjugate Acid the substance formed when a proton is added to a base
Conjugate Base the remaining substance when a proton is lost from an acid
Conjugate acid-base pair two substances related to each other by the donating and accepting of a single proton
Hydronium Ion H3O+
Strong Acid an acid that completely dissociates to produce H+ ions in a solution
Weak Acid an acid that dissociates to a slight extent in aqueous solution
Diproctic Acid an acid that can furnish two protons
Oxyacid an acid in which the acidic proton is attached to an oxygen atom
Organic Acid an acid with a carbon atom backbone and a carboxyl group
Amphoteric Substance a substance that can behave either as an acid or as a base
pH scale a convenient way to represent solution acidity Input in calculator: pH = -log [H+]
Indicators (acid-base) a chemical that changes color depending on the pH of a solution
Indicator Paper a strip of paper coated with a combination of acid-base indicators
pH meter a device used to measure the pH of a solution
Neutralization Reaction an acid-base reaction
Titration a technique in which a solution of a known concentration is used to determine the concentration of another solution
Standard Solution a solution in which the concentration is accurately known
Buret a device used for the accurate measurement of the delivery of a given volume of a liquid or solution
Stoichiometric Point (equivalence point) the point in a titration when enough titrant has been added to react exactly with the substance in a solution that is being titrated
Acids a substance that produces hydrogen ions (H+) in an aqueous solution; a proton donor
Bases a substance that produces hydroxide atoms (OH-) in solution; a substance that accepts a proton
Arrhenius concept of acids and bases acids produce hydrogen ions (H+) in solution; bases produce hydroxide ions (OH-) in solution
Brønsted-Lowry Model an acid is a proton (H+) donor and a base is a proton acceptor
Titration Curve (pH curve) a plot of pH of solution versus volume of titrant added to a given solution
Buffered Solution a solution that resists a change in pH when either an acid or a base are added
