Titration Curve Terminology

Question 0

Endpoint

Answer 0

Pt in rxn where a shallow/steep drop occurs (indicated by color change-intermediate color)

Question 1

Buffering region

Answer 1

Horizontal part of graph where small amounts of acid & base are reacted
pH remains unchanged
**always at the beginning of curve”
# of buffering regions are 1 less than # of curves

Question 2

Equivalence point

Answer 2

Pt at which chemically equivalent amounts of acid and base are present

of equivalence pts = # of rxns

Question 3

Indicator

Answer 3

Choose within equivalence pt in color range

Question 4

Types of graphs

Answer 4

Monoprotic SA & SB- steep drop, pH=7 at equiv pt

WA/WB- shallow slope, equiv pt shifted to stronger species

Polyprotic acids/bases-show all rxns when quantitative
