Titration Analysis

Question 1

Define titrant

Answer 1

The solution within the burette

Question 2

Define sample

Answer 2

A measured fixed volume of solution in which titrant is added

Question 3

Define burette

Answer 3

A precisely marked glass cylinder with a stopcock at one end

Question 4

Define equivalence point

Answer 4

The point at which the exact theoretical amount of titrant has been added to completely react with the sample

Question 5

Define endpoint

Answer 5

The point during a titration when this sudden change in some observable property of the solution, such as colour, pH or conductivity

Question 6

Define standard solution

Answer 6

A solution of highly certain concentration

Question 7

Define primary standard

Answer 7

A chemical that can be obtained at high purity, with mass that can be measured to high accuracy and precision

Question 8

Define “standardizing a solution”

Answer 8

Means finding the concentration of solution after it is prepared by reacting it with another solution that has been prepared from a primary standard

Question 9

How many trials must be completed? Any requirements?

Answer 9

At least 3 trials within values that are all within a range of 0.2ml

Question 10

Define titration

Answer 10

The process of carefully measuring and controlling the addition of a solution called a titrant from a burette into a measured fixed volume of another solution called a sample.
