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.
HDL Cholesterol Level There is also something called HDL (High Density Lipoprotein) Cholesterol, which is often referred to as good cholesterol. The higher the HDL Cholesterol the better.HDL Cholesterol levels of 60 mg/dL or more are considered good. HDL Cholesterol levels of less than 40 mg/dL are considered very bad.owever, too much is bad. HDL Cholesterol is considered good, because it removes the bad LDL Cholesterol. Be aware that the Total Cholesterol result by itself may not be enough information for knowing if you have healthy cholesterol levels, because it adds up HDL, LDL, and VLDL.
