Acid-Base Study Guide
to Study:
 Definition of acids and bases
 Identify the acid, base, conjugate acid or conjugate base in an equation
 Distinguishing chemical/physical properties of acids and bases
 Anthocyanin cabbage juice lab
 Chemical equation for ocean acidification and understand how/why it occurs
 Acids/bases in daily life (foods, bats, etc.)
 Neutralization reactions (reactants, products), how to conduct a titration experiment
 Definitions: monoprotic, diprotic, polyprotic, amphoteric, neutralization, indicator
You will be given an equation sheet for this assessment. No Notecard.
