This video tutorial is in the Education category which will show you how to make sodium bromate and potassium meta-periodate. This experiment uses toxic chemicals and releases harmful gases. First you have to make a saturated sodium bromide. To this solution then add a small amount of potassium dichromate. The solution now becomes concentrated. Then make the circuit as shown in the video. You need a 3 - 5 ohm resistor in order to reduce the current. Then let the cell run for around 6 hours. Stir the solution periodically and add more water if required. After that put it in an ice bath then filter and wash the crystals.
