Assuming that 1.0g of nahco3 is reacted with excess hcl and completely converted to nacl calculate the mass of nacl obtained
Blood glucose levels are measured by a procedure based upon the enzyme glucose oxidase. Since an enzyme is used, it is very specific for only D-glucose, and will not be subject to interferences from other molecules in the blood. Glucose is a reducing sugar, which means that it can be oxidized. How the tests for Blood Glucose (random and HbA1c) are conducted based on the reducing nature of monosaccharides?
