1

molarity

moles of solute/ liters

New cards
2

moles solute =

mmol x liters

New cards
3

mmol solute=

M x mL

New cards
4

equivalence point

when moles of acid and bas are equal

New cards
5

indicator

chemical in a titration what undergoes a physical change to signify the equivalence point

New cards
6

at ½ equivalence point pH=

pKa

New cards
7

calculation before the titration

ICE table and weak acid equilibrium equation to find Ka

New cards
8

calculation after titration started but before equivalence point

buffer question, Henderson Hasselbach

New cards
9

calculation at equivalence point

100% of weak acid is weak base, use ICE and weak base equilibrium, find Kb from Ka

New cards
10

calculation after equivalence point

strong base equation

New cards
11

how to determine concentration of unknown at equivalence point

dividing moles of acid by volume of unknown
