9/100 = 12 / (100 +x) so 0.09 (100+x) = 12 so 9 +0.09x =12
therefore 0.09x = 12-9 and thus x = 3/0.09 = 33.334
So to 100g of 12% peroxide would need to add 33.34 g water.
To put another way to every 3 parts peroxide add 1 part water.
Ratio of 3:1 peroxide:water
To dilute 12% hydrogen peroxide to 9%, you would need to mix it with water in a specific ratio. To decrease the concentration to 9%, you should add approximately 2 parts of water to 1 part of the 12% hydrogen peroxide solution. This will result in a final solution with a concentration of around 9%.

Can you make 12 percent peroxide using 9 percent peroxide?
To create a 12% solution from a 9% solution, you can mix the 9% peroxide with a concentrated hydrogen peroxide solution to increase the concentration. The specific volumes needed would depend on the concentrations of the starting solutions and the final volume desired. It's important to handle concentrated hydrogen peroxide with caution and use appropriate safety measures.
Can you make 12 percent peroxide with 9 percent peroxide?
To create a 12% peroxide solution from a 9% peroxide solution, you can mix the 9% solution with water in the appropriate ratio to increase the concentration. Since we are increasing the concentration, you would need to add a larger proportion of the 9% solution than water, following the principles of dilution. Calculations can be done by setting up a simple dilution equation.
What is 25 percent of 3 lb 9 oz?
To find 25% of 3 lb 9 oz, first convert 3 lb 9 oz to ounces (48 oz), then calculate 25% of 48 oz, which is 12 oz. Convert 12 oz back to pounds and ounces. The result is 12 oz = 0 lb 12 oz. So, 25% of 3 lb 9 oz is 0 lb 12 oz.
How do you dilute trypsin10x?
To dilute trypsin 10x, you can combine 1 part of the 10x concentrated trypsin solution with 9 parts of a suitable diluent, such as PBS or cell culture media. For example, add 1 mL of the 10x trypsin to 9 mL of the diluent to obtain a 1x trypsin solution. Mix thoroughly before use.
How do you dilute formalin?
To dilute formalin, you can mix it with water in the desired ratio. For example, to create a 10% formalin solution, mix 1 part formalin with 9 parts water. Always handle formalin carefully as it is a hazardous chemical and follow proper safety protocols.
What is the difference between 6 percent 9 percent and 12 percent peroxide?
The difference between 6%, 9%, and 12% Hydrogen Peroxide solution is the Hydrogen content.
Can you make 12 percent peroxide using 9 percent peroxide?

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 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.
