Volumetric Analysis

Question 1

Volumetric analysis involves

Answer 1

Carrying out a titration; during the titration, a chemical reaction takes place

Question 2

What is a quantitative reaction

Answer 2

One which goes to completion i.e. all of the reactants are converted to products according to the balanced equation

Question 3

What is a standard solution

Answer 3

A solution of accurately know concentration

Question 4

What is titration used to determine

Answer 4

The volumes of solution required to reach the end-point of a chemical reaction, accurately

Question 5

What is the end point of a reaction

Answer 5

The point at which the reaction is just complete

Question 6

How is the end point of a reaction indicated

Answer 6

Using indicator that changes colour

Question 7

Acid-base titrations

Answer 7

• based on neutralisation reactions

- use pH indicator solutions

Question 8

Concordant

Answer 8

Titre volumes within 0.2 cm^3

Question 9

Redox titrations

Answer 9

Based on redox reactions

Question 10

Why is indicator not needed for titrations using acidified permanganate

Answer 10

Purple permanganate solution turns colourless when reduced (it is self indicating)
