If you will use 1 Liter of hydrogen peroxide to disinfect the floor, how much water should you use to mix it with?

The correct answer is 1 liter of water. When disinfecting with hydrogen peroxide, it is often recommended to dilute it in a certain ratio depending on the concentration of the hydrogen peroxide being used and the intended use for disinfection. If the instruction is to mix 1 liter of hydrogen peroxide, typically you would add an equal amount of water to achieve effective disinfection while minimizing the harshness of the solution.

Using 1 liter of water along with 1 liter of hydrogen peroxide would give a balanced mixture that can effectively disinfect surfaces without being overly concentrated. This is particularly useful for practical applications like floor disinfection.

The other options suggest different volumes of water that would either increase the dilution excessively or not provide enough liquid to properly mix with the hydrogen peroxide for efficient disinfection. Hence, 1 liter of water is the most appropriate choice for mixing in this case.
