what is the colour of ferrous sulphate crystal? how does this colour change after heating
Answers
Explanation:
On heating, ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So their colour changes from light green to white. On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur trioxide (SO3).

Procedure:
Real Lab Procedure:
Take about 2g of ferrous sulphate crystals in a dry boiling tube and note the colour of the crystals.
Hold the boiling tube with a test tube holder and heat the boiling tube over the flame of a burner.
Smell the gas being emitted.
Observe the colour of the crystals after heating.
To use the simulator:
You can select the type of reaction form ‘Select the type of reaction’ drop down list.
Thermal Decomposition
You can select the sample form ‘Select the sample’ drop down list.
To start the experiment, click on the ‘Start’ button.
To put copper carbonate into the test tube, drag the spatula over the test tube.
To turn on the burner, click on the knob of the burner.
To heat the contents of the test tube, drag the test tube over the burner.
Wait for some time to complete the reaction.
