Final answer:
Heavy soiled hose must be washed with a high concentration liquid soap solution, typically given as a percentage.
Step-by-step explanation:
Heavy soiled hose must be washed with a high concentration liquid soap solution. The concentration of the liquid soap solution is typically given as a percentage.
For example, hydrogen peroxide is commonly labeled as a 3% by volume solution. This means that for every 100 mL of the solution, 3 mL is hydrogen peroxide.
In the case of liquid bleach, it is an aqueous solution of sodium hypochlorite (NaOCI). The concentration of bleach is usually given as a percentage by mass. For instance, a typical liquid bleach bottle may cite a concentration of 7.4% NaOCl by mass, which means that a 100.0-g sample of bleach contains 7.4 g of NaOCI.
