How to prepare 5% potassium persulphate?

 Prepare 5% Potassium Persulphate(K2S2O8)

To prepare  5% potassium persulfate solution, you will need:

• Potassium persulfate (also known as potassium peroxydisulfate)
• Distilled water

Here's one way you could prepare the solution:

• Weigh out 50 grams of potassium persulfate.
• Slowly add the potassium persulfate to a container of 1000 milliliters of distilled water.
• Stir the mixture until the potassium persulfate is fully dissolved.
• If necessary, adjust the volume of the solution to 1000 milliliters with distilled water.

Note: It's important to use distilled water, as impurities in tap water can affect the activity of potassium persulfate.
