Using Bleach as a Disinfectant - Northeastern University

Feb 21, 2017 · The dilution ratio of bleach to water is dependent on the concentration of sodium hypochlorite because the final bleach solution should have a NaClO concentration between 0.5 and 2.0% or 5,000 to 20,000 ppm. Bleach irritates mucous membranes, the skin and the respiratory system. It also reacts readily with

DILUTION CHART - picdfw.com

DILUTION CHART Some numbers are rounded up or down to make measuring easier PIC’s dilution ratios are written as parts. Therefore, when PIC’s label suggest a dilution ratio of 1-to-4 (1:4) that means 1 part product and 4 parts water. Some people calculate dilution by dividing by 4 (in this example), which is an incorrect answer.
