Thus, Cu(NO3)2 and Fe(NO3)3 are soluble. 3. The chloride (Cl-), bromide (Br-), and iodide (I-) ions generally form soluble salts. Exceptions to this rule include salts of the Pb2+, Hg22+, Ag+, and Cu+ ions. ZnCl2 is soluble, but CuBr is not. A salt is soluble if it dissolves in water to give a solution with a concentration of at least 0.1 moles per liter at room temperature. 2  A salt is insoluble if the concentration of an aqueous solution is less than 0.001 M at room temperature. 3  Slightly soluble salts give solutions that fall between these extremes.
Lipid is a medical term for fat found in the bloodstream. There are different types of lipids, some good and some bad.igh density lipoprotein cholesterol (HDL-C). HDL-C is known as the âgoodâ cholesterol because it helps take âbadâ cholesterol out of the body. Think about HDL-C as a âtow truckâ that removes LDL-C from your blood.
Lipids are one of the four major groups of organic molecules; the other three being proteins, nucleic acids (DNA), and carbohydrates (sugars). Lipids are made up of the same elements as carbohydrates: carbon, hydrogen, and oxygen.ipids and Fats. 1  What are fats? 2  Fats are composed of a glycerol molecule and three fatty acid molecules. 3  Are all fats bad? 4  No, as a matter of fact, fats are needed by our bodies to be healthy. 5  Types of Fats. 6  There are two main types of fats: saturated fats and unsaturated fats. 7  Saturated Fats-Saturated fats are solids at room temperature. 8  Unsaturat
