Question
Map Sapling Learning macmillar learning Classify each titration curve as representing a strong acid titrated with a strong base, a strong base titrated with a strong acid, a weak acid titrated with a strong base, a weak base titrated with a strong acid, or a polyprotic acid titrated with a strong base Strong base strong acid Strong acid/ Weak acid/ Weak base/ strong acid Polyprotic acid/ strong base mL of titrant mL of titrant mL of titrant mL of titrant mL of titrant O Previous 8 Give Up & View Solution Check Answer Next ExtExplanation / Answer
Number from:
left to right, 1,2,3,4,5
a)
storng acid+ strong base --> no buffer region, pH = 7 neutral, steepest change in pH. Expect initial pH to be ph <7 due to acid
from the list, the best answer is 5
b)
strong base + strong acid --> no buffer region, pH = 7 neutral, steepest change in pH. Expect initial pH to be ph >7 due to base
from the list, the best answer is 2
c)
weak acid --> ph < 7
expect buffer region, pH > 7 in equivalence point
form the list
best option is 3
d)
weak base --> ph > 7
expect buffer region, pH < 7 in equivalence point
form the list
best option is 1
e)
polyprotic acid --> Reuqires at least 2 points in equivalneces
the best answer is 4
