Calcium carbonate label. An example of the type of labelling used on laboratory chemicals. The information provided shows the assay results for calcium carbonate solution. An assay is a procedure whereby a property or concentration of a particular chemical is measured. Labels showing assay test results enable the person using the chemical to know its exact make-up and concentration. This is important as such properties can affect the outcome of chemical reactions.
