Question

tell me the steps of briggs-rauscher reaction

Answer 1

Solutions

Solution A:
Add 43 g potassium iodate (KIO3) to ~800 mL distilled water. Stir in 4.5 mL sulphuric acid (H2SO4). Continue stirring until the potassium iodate is dissolved. Dilute to 1 L.
 Solution B:
Add 15.6 g malonic acid (HOOCCH2COOH) and 3.4 g manganese sulphate monohydrate (MnSO4 . H2O) to ~800 mL distilled water. Add 4 g of vitex starch. Stir until dissolved. Dilute to 1 L.
Solution C:
Dilute 400 mL of 30% hydrogen peroxide (H2O2) to 1 L.

Materials

300 mL of each solution
1 L beaker
stirring plate
magnetic stir bar

Procedure

Place the stirring bar into the large beaker.
Pour 300 mL each of solutions A and B into the beaker.
Turn on the stirring plate. Adjust the speed to produce a large vortex.
Add 300 mL of solution C into the beaker. Be sure to add solution C after mixing solutions A + B or else the demonstration will not work.

That's it. You're done
