First, it is necessary to prepare three solutions, in large beakers:
- Add 210 ml of distilled water to 120 ml of 30% hydrogen peroxide solution. Measure volumes using measuring cylinders.
- Pour 14.3 g of potassium iodate into a beaker and add 200 ml of water. Due to the low solubility in water, potassium iodate solution must be heated on a hot plate. Then, add 1.5 ml of concentrated sulfuric acid. Further, it is necessary to increase the volume of the solution to equal to about 0.33 liters.
- Take a sample of manganese sulfate (3 g). Next, add 5.2 g of malonic acid. Then add 230 ml of distilled water. Then, it is necessary to add a small amount of pre-cooked starch paste solution and increase volume of the solution to equal to about 0.33 liters.
To perform the reaction.
- Immerse a magnetic stirrer in the third glass and set to shuffle.
- Next, add the second solution to the third solution, and finally the first.
- Thereafter the reaction begins.
