How do you prepare 3 percent of hydrogen peroxide from 30 percent of hydrogen peroxide?

Answer 1

To prepare 3% hydrogen peroxide from 30% hydrogen peroxide, you need to dilute the 30% solution with water. The formula to calculate the dilution is C1V1 = C2V2, where C1 is the initial concentration (30%), V1 is the volume of the initial solution, C2 is the final concentration (3%), and V2 is the final volume of the solution you want to prepare. By plugging in the values, you can determine the volume of 30% hydrogen peroxide needed and the volume of water needed to achieve a 3% solution.

Answer 2

Lets say you want an end volume of 500 ml of 3% peroxide. But you dont know how much 30% peroxide to use.

Concentration1 X Volume1 = Concentration2 X Volume2

30/100 X unknown ml = 3/100 X 500 ml

unknown ml = 50 ml

50ml of 30% added to pure 450 ml of water = 500 ml 3 % peroxide.

Answer 3

To prepare 3% hydrogen peroxide from 30% hydrogen peroxide, you would need to dilute the 30% solution by adding approximately 9 parts water to 1 part of the 30% solution. For example, mix 1 mL of 30% hydrogen peroxide with 9 mL of water to achieve a 3% solution. Always add the water to the hydrogen peroxide and not the other way around to avoid splashes.
