Water to coke

Introduction

Are you tired of drinking water? Step into the future and change it to coke (non-drinkable).

Description of the Experiment

In this experiment, you will need to make three separate solutions, labelled A, B and C. Solution A: Dissolve 0.66g of starch in 75 mL of boiling water. Solution B: Dissolve 3.53g potassium iodate in 75 mL of water. Solution C. Dissolve 1.13g of sodium disulfite in 75 mL of water.

Put 1890 mL water to the coke flask. Add 22 mL of solution A to the flask, then add 44 mL of solution B and 6 drops of the sulfuric acid. Finally, add 44 mL of solution C, close the flask and shake well for few seconds. Put the flask on a table and wait for few awkward moments. If successful, the solution in the flask will turn from a clear solution to deep black in a blink of an eye.

Safety Information

While handling the concentrated sulfuric acid, wear a lab coat, goggles and gloves.
