Color changing reaction

This was a lab that my students did. They mixed a few colorless solutions to make one solution that changes colors. It was a bit hit.

1.  Potassium Iodate, Sulfuric Acid, and Water

2. 30% Hydrogen peroxide solution

3. Malonic Acid, Manganese sulfate monohydrate, starch and water

@joelarrington89 if you want that rich deep ultramarine colour, you put it up to 30% but whenever we do this at school we have to put it to about 10% which is a bitch

Where can I purchase the said ingredients?

Thanks!

[joelarrington89]

we diluted the hydrogen peroxide to 6%

Could you be more specific? ie. moles/molality/%/ratios

[obituaryu]

holy potion

[dangreen777]

What is the ratio of the compounds in each solution?

What is the ratio of the solutions?
