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.
Not all cholesterol is bad for the body. There are two types of cholesterol-HDL (High Density Lipoprotein or good cholesterol) and LDL (Low Density Lipoprotein or bad cholesterol).While LDL causes blockage in arteries, HDL helps transport triglycerides to the liver for excretion.ecommended level of good cholesterol is 1.55 mmol/L and above. The recommended level of LDL (bad cholesterol) is 2.6 mmol/L or lower. Sources. Sources of HDL include onions and Omega-3 fatty acids like flax oil, fish, foods rich in fibre like grains, oats, bran etc.
