How do you prepare a 1:100 bleach solution?

To prepare a 1:100 bleach solution, you need to mix one part of bleach with 99 parts of water. This mixture creates a dilution that is commonly used for disinfecting and sanitizing purposes. The ratio of 1:100 means that for every single unit (such as milliliter or ounce) of bleach, there are 99 units of water, resulting in a total of 100 units of solution.

This precise dilution is crucial in ensuring the solution is effective while also being safe for use, as concentrated bleach can be hazardous. Other proposed methods, such as adding 99 parts of bleach to 1 part of water, would create a solution that is much more concentrated—that would not achieve the desired dilution ratio for effective disinfecting purposes.
