How do you prepare 3 percent of hydrogen peroxide from 30 percent of hydrogen peroxide?
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.
How do you prepare 0.2 M hydrogen peroxide?
Oh, dude, preparing 0.2 M hydrogen peroxide is like making lemonade, but with a bit more chemistry. You just take the concentrated hydrogen peroxide solution and dilute it with water until you reach a concentration of 0.2 M. It's not rocket science, just mix and measure, like following a recipe for a boring science experiment.
How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare 6 nM ammonium hydroxide a 30 percent solution you need to know the volume of the 30 percent solution that you have and the volume of 6nM solution you would like to make. Then use the following formula: C1V1 = C2V2 where C = concentration in moles/Liter and V = volume in liters.
How do you prepare 1 percent iodine solution?
To prepare a 1% iodine solution, you can mix 1 part iodine with 99 parts water (for example, 1 mL iodine to 99 mL water). Ensure proper handling and measuring equipment to accurately dilute the iodine. Remember to always label the solution properly for safety and tracking purposes.
What are 3 ways to prepare hydrogen?
You can prepare hydrogen by adding magnesium to hydrochloric acid. hydrochloric acid + magnesium = magnesium chloride + hydrogen.

How do you prepare 1 percent solution of hydrogen peroxide?
Fractional crystalization of Hydrogen Peroxide would involve lowering the temperature of the solution to just above the melting point. This will depend on the concentration and it is NOT linear. For instance, a 3% solution as is found in most drugstores will freeze at about -2C, 30% at about -25C, 35% at -33C, 50% at -52C, 70% at -40C and finally 90% at about -11C.
Why most of the times hydrogen peroxide is prepared by using barium peroxide?
Barium peroxide is commonly used to prepare hydrogen peroxide because it readily decomposes in the presence of water, releasing oxygen gas which then reacts with hydrogen to produce hydrogen peroxide. This method provides a simple and efficient way to produce hydrogen peroxide on a small scale.
How do you prepare trifluoroperacetic acid?
by urea hydrogen peroxide reaction with tri fluro acetic anhydride
How do you prepare 30 percent sucrose solution?
See the two Related Questions to the left for the answer.The first is how to prepare a solution starting with a solid substance (and dissolving it). The second question is how to prepare a solution by diluting another solution.

How do you prepare 300 micro molar H2O2 using 3.0 percent H2O2?
Too many unknowns in your question. Is this 3% by mass or by volume? Does the quantity of final solution matter? IE do you need 100 ml, 1 liter or 5000ml. What is the density of the hydrogen peroxide? (needed for a volume % problem) Assuming you mean 3% by mass, then that means 3 g of hydrogen peroxide in 100 g of solution. 300 micromolar = 3 x 10-4 molar. Assuming you want to make one liter then you need 3 x 10-4 moles of peroxide. The molar mass of peroxide is 34 g/mole. 34 g/mole x 3 x 10-4 moles = 1.02 x 10-2 grams of peroxide 1.02 x 10-2 grams / .03 = 0.34 grams of the original solution. Weigh (mass) accurately 0.34 g of the original solution in a 1 liter volumetric flask. Add distilled water until the total volume is 1 liter.
How do you prepare h2o9?
Given that hydrogen peroxide (H2O2) decomposes easily into water and oxygen, H2O9 would probably not be possible to synthesize in real life.
How do set up an experiment to measure the effect of temperature on catalase?
Create a control group by placing a measured amount of catalase solution in a test tube. Prepare test tubes with catalase solution at varying temperatures (e.g., using water baths at different temperatures). Add a known amount of hydrogen peroxide to each test tube and measure the rate of oxygen gas production as the catalase breaks down the hydrogen peroxide. Record and compare the rate of reaction at different temperatures to determine the effect of temperature on catalase activity.
