Recipe for Dakin’s Solution
Ingredients
To prepare Dakin’s solution, you will need the following ingredients:
– Potassium permanganate (KMnO4)
– Sodium metabisulfite (Na2S2O5)
– Distilled water
Instructions
1. Measure the Potassium Permanganate: The concentration of potassium permanganate in Dakin’s solution is typically 1% (w/v). To prepare 100 ml of the solution, you will need 1 gram of potassium permanganate.
2. Dissolve the Potassium Permanganate: Add the potassium permanganate to a clean, dry beaker. Gradually add distilled water while stirring until the potassium permanganate is completely dissolved.
3. Measure the Sodium Metabisulfite: The concentration of sodium metabisulfite in Dakin’s solution is typically 0.5% (w/v). To prepare 100 ml of the solution, you will need 0.5 grams of sodium metabisulfite.
4. Dissolve the Sodium Metabisulfite: Add the sodium metabisulfite to the beaker containing the potassium permanganate solution. Stir until the sodium metabisulfite is completely dissolved.
5. Stir the Solution: Continue stirring the solution for a few minutes to ensure that the ingredients are well mixed.
6. Store the Solution: Transfer the solution to a clean, sterile container with a tight-fitting lid. Store the solution in a cool, dark place.
