Neutralisation Titration

Question 1

What is titration?

Answer 1

Titration is a laboratory technique used to determine the concentration of an acid or base by reacting it with a solution of known concentration.

Question 2

True or False: In a titration, the endpoint is the point at which the reaction is complete.

Answer 2

True

Question 3

Fill in the blank: The solution with a known concentration in a titration is called the _______.

Answer 3

titrant

Question 4

What is the purpose of using an indicator in titration?

Answer 4

An indicator is used to signal the endpoint of the titration, often by changing color.

Question 5

How do you calculate the concentration of an acid after titration?

Answer 5

Concentration of acid = (Concentration of titrant × Volume of titrant) / Volume of acid.

Question 6

Multiple Choice: Which of the following is a common indicator used in acid-base titrations? A) Phenolphthalein B) Methyl orange C) Bromothymol blue D) All of the above

Answer 6

D) All of the above

Question 7

What is the role of the burette in a titration?

Answer 7

The burette is used to deliver the titrant in a controlled manner to the analyte.

Question 8

True or False: The volume of the titrant used is irrelevant in calculating the concentration of the acid.

Answer 8

False

Question 9

Fill in the blank: The point at which the amount of acid equals the amount of base in a titration is called the _______.

Answer 9

equivalence point

Question 10

What is the significance of the dilution factor in titration calculations?

Answer 10

The dilution factor is important to accurately determine the concentration of the original solution if it was diluted before titration.
