Aim: To identify and correct chemical incompatibility between oxidizing and reducing agents
Apparatus required: Spatula
Formula:
| Ingredients | Official Formula | Working Formula |
|---|---|---|
| Potassium chlorate | 10g | 500mg |
| Tannic acid | 5g | 250mg |
| Sucrose | 5g | 250mg |
Principle:
An oxidizing and a reducing agent when mixed by a process involving friction results in violent explosion. Explosion is due to Redox reaction between the ingredients. Since potassium chlorate is an oxidizing agent and tannic acid is a reducing agent the preparation becomes a classical example of chemical incompatibility can be corrected by employing a mixing process that avoids friction, such as tumbling or spatulation.
Procedure:
- Mix in excess potassium chlorate and tannic acid on a butter paper by spatulation
- Add sucrose to the above mixture and mix well
- Weigh 1g of blend and pack by double wrap technique
- Dispense in a labeled envelop
- Discard the excess powder blend
Category: Antiseptic and astringent
Storage: Store in cool and dry place
Direction: Add the powder in a glass of warm water and use as gargle.
