WebYou add some DDT to 250.0 mL water (assume that DDT is soluble in water at this concentration), and then add 100 mL of octanol to a vessel containing the aqueous DDT solution. You then allow this system to come to equilibrium. You measure the DDT in the aqueous phase and obtain a concentration of 4.08 x 10-3 M . WebDDT is very poorly soluble in water. For all practical purposes, this compound is insoluble in water. The solubility of dichlorodiphenyltrichloroethane in water corresponds to 25 …

WebSince DDT is not soluble in water, it is not washed away by the rain, adding to its persistence in the environment. But since DDT is lipid-soluble, it tends to concentrate in the body fat of animals. The following sequence of events shows how DDT can become a problem for many animals in a food web.
WebSolubility means whether it can dissolve in water or lipids. Lipids are a type of fat. For example, butter is not water soluble - if you mix butter and water, the butter floats on top of the water because it cannot mix in. DDT is not very soluble in water, so it gets stored in fats and can remain in the body for a very long time.
