Theory: The percentage purity of a sample solution can be determined by using a volumetric method. In this method, a known volume of a standard solution is added to the sample solution until the reaction is complete. The amount of …
Theory Volumetric analysis is a quantitative chemical analysis technique used to determine the concentration of an unknown solution by measuring the volume of a solution of known concentration required to react completely with the unknown solution. In this experiment, the …
