A 10 percent bleach solution typically remains effective for disinfection purposes for up to 24 hours. After this period, the solution may lose its potency and effectiveness in killing germs and bacteria. It is recommended to prepare fresh bleach solution daily for optimal disinfection.
To make a 5% bleach solution from an 8.25% solution, you can use the dilution formula (C_1V_1 = C_2V_2), where (C_1) is the concentration of the stock solution (8.25%), (V_1) is the volume of the stock solution you need, (C_2) is the desired concentration (5%), and (V_2) is the final volume of the diluted solution. For example, to make 100 ml of a 5% solution, you would calculate (V_1 = \frac{C_2 \times V_2}{C_1} = \frac{5 \times 100}{8.25} \approx 60.61) ml of the 8.25% solution. Then, add enough water to reach a total volume of 100 ml.
0.0362 x 1911.9 g = 69.2 g NaOCl (to 3 significant figures based on 0.0362).
A proper bleach solution for disinfecting in the kitchen is made by mixing 1 tablespoon of bleach with 1 gallon of water. Ensure it is prepared fresh daily as bleach loses its disinfecting power over time. Use caution and ensure proper ventilation when working with bleach.
A weak solution of bleach is a diluted mixture of bleach with water. This reduced concentration is commonly used for household cleaning tasks and disinfecting surfaces. It is important to follow instructions for proper dilution to ensure safe and effective use.
You dillute it with some more of the same solvent used for the 6 percent solution - pressumably water.

The mass of sodium hypochlorite in 2,5 kg solution is 131,25 g.
Polyester will not bleach if exposed to a bleach solution.
Start with a ratio of 1 part bleach to 10 parts water for a light fade effect. For a 50 percent bleach solution, you can use a 1:1 ratio of bleach to water to achieve a stronger fading effect. Test on a small, inconspicuous area of the fabric first to ensure the desired result.
7x/10 (That's 7/10 times x). So if x = 10 gallons, then there are 7 gallons of bleach in the solution. (7gal/10gal = 0.70 = 70%). This answer if correct if the percentage is by volume. Otherwise, the question can not be answered without knowledge of the basis of the percentage.
When using hydrogen peroxide or bleach, a 3% solution is 50% stronger than a 2% solution. Be very careful when handling these chemicals, and don't get ammonia in the bleach, or you will release toxic clouds of gas.
If the percent by mass of sodium hypochlorite (NaClO) in the bleach solution is 5.24%, then 100% - 5.24% = 94.76% is the water weight. For a 2500.0g solution, the mass of NaClO is 5.24% of 2500g = 131g. Since the remaining mass is water, the mass of NaCl (sodium chloride) in the solution would be zero.

To make a 20 percent bleach solution, you'll need to mix 1 part of concentrated bleach (usually around 5-6% sodium hypochlorite) with 4 parts of water. For example, if you use 1 cup of bleach, add 4 cups of water. Always add bleach to water, not the other way around, to minimize splashing. Make sure to wear gloves and work in a well-ventilated area for safety.
Add three times as much water as you have bleach.
