The Factors that Affect the Temperature Change Between Copper Sulphate and Iron Filings

Aim

The aim of this piece of coursework is toinvestigate the factors that

affect the temperature change between Copper Sulphate and Iron

filings.

Affecting factors

Ø The concentration of Copper Sulphate Solution (CuSO4)

Ø The amount of Iron filings (Fe) used

I have chosen to experiment using the 1st factor I will have to change

the concentration of the Copper Sulphate Solution (CuSO4)

Prediction

I predict that the higher the concentration of CuSO4 the higher the

concentration the higher the temperature rise. I therefore predict the

higher the concentration the higher the temperature change.

Background knowledge

I know that when I add the iron filings to the solution the iron will

displace the Copper here is a diagram to show the reaction.

Controlled variables

Ø The same mass of Iron filings

Ø The same volume of copper sulphate solution

Variables

Ø Concentration of the Copper Sulphate (CuSO4)

Safety

Ø Wash hands if you get all copper sulphate solution on them

Ø Wear Safety glasses just in case you get either copper sulphate

solution or iron filing in your eyes

Ø Put stools out of the dangerous positions

Apparatus

Ø Boiling tube

Ø Clamp and stand

Ø Small beaker

Ø Measuring cylinder

Ø Scales

Ø Paper

Ø Copper Sulphate Solution

Ø Water

Ø Iron Filings

Method

Ø Use a measuring cylinder to measure 10cm3 of Copper Sulphate

Ø Put it into the boiling tube

Ø Use a thermometer to take the initial temperature

Ø Weigh 2g of iron filings onto a piece of paper

Ø Quickly put them into the boiling tube and instantly begin to stir

until the reaction has finished

Ø When the reaction finishes the temperature will be at a peek record

this temperature
