chapter 17.3 - titration

Question 1

pH depends on…

Answer 1

H+ concentration only

Question 2

for strong acid and strong base titration pH before the equivalence point…

Answer 2

is determined by concentration of acid not yet neutralized

Question 3

for strong acid and strong base titration pH at equivalence point…

Answer 3

is 7 bc equal moles of NaOH and HCl.

Question 4

for strong acid and strong base titration pH after equivalence point…

Answer 4

determined by the concentration of excess NaOH in solution

Question 5

for weak acid and strong base titration initial pH…

Answer 5

determined by using Ka of CH3COOH

Question 6

for weak acid and strong base titration the pH before the equivalence point…

Answer 6

determined using procedures from common ion effect

Question 7

for weak acid and strong base titration the pH at the equivalence point…

Answer 7

depends on CH3COO- bc it’s a weak base; likely greater than 7

Question 8

for weak acid and strong base titration the pH at the equivalence point…

Answer 8

relative to the amount of excess OH- in the solution
