Mn(7+) is reduced to Mn(2+) going from purple to colourless/pale pink. The Fe(2+) ions are oxidised to Fe(3+) ions to complete the redox reaction.

Colour of aqueous iron 2 sulphate before potassium iodide is added?
Pale green
Why does the color with sulphate change?
This is because sulphate is a thing that just dissolve in the water and changes the colour.
How would you test for the presence of sulfur Dioxide?
You can attempt to pass the gas into aqueous acidified potassium manganate(VII). Sulfur dioxide turns it from purple tocolourless.It forms a white precipitate of barium sulphate when passed through a solution of barium chloride and chlorine water.
What is the colour change when sodium hydroxide is added to iron II sulphate?
dark green (but orange - brown if left standing)
Does copper sulphate undergo any physical or chemical changes during heating?
On heating penta hydrated copper sulphate undergoes dehydration and changes colour from blue to white that means physical change but on heating it does not show a chemical change.

What colour is potassium bromide solution?
The colour of aqueous potassium permanganate ranges from violet to lighter shades of purple depending on its concentration.Please see the related link below to see an image bench scale testing of potassium permaganate showing the range of colour that it can appear.
When sulphuric acid is added to sodium bicarbonate why does the colour change?
this makes sodium sulphate and CO2
What is the colour of aluminium sulphate solutions?
aluminum sulphate is colourless
What colour is sulphate dissolved in water?
You have to specify the sulphate of which element.
What colour is copper iodide and potassium sulphate?
Potassium sulfate would be colorless; copper iodide is probably blue or green (I don't know which off the top of my head, but copper salts are generally either blue or green).
