Titrations

Question 1

What do titrations allow you to do

Answer 1

They allow you to find out exactly how much acid is needed to neutralise a quantity of alkali

Question 2

How do you determine when an end point of a titration has been reached

Answer 2

The indicator would have changed colour

Question 3

What are the steps to carry out a titration

Answer 3

1.Use a funnel to fill a burrete with some acid of known concentration,record the initial volume of acid in the burette

2.In a conical flask add an alkali and an indicator

3.Using the burette add the acid to the alkali a bit at a time giving the conical flask a swirl as it goes

4.When you reach your end point stop the flow and record the final volume of acid in the burette

5.Use this recording along with the initial volume to decide how much acid was needed

Question 4

What sort of titration should you do first

Answer 4

A rough titration

Question 5

Within your repeats how close should the measurements be to each other

Answer 5

Within 0.10cm cubed of each other
