The purpose of the volumetric glassware experiment is to study the measurement of the actual volume contents in 3 different types of volumetric glassware (50 ml beaker, 10 ml pipette, 50 ml burette)
Analytical chemistry is a science that trying to answer questions (how much of the substance exist in a matter and what is it). To precisely answer these questions scientists should use accurate equipment which is called laboratory glassware. The accuracy is the nearness of the true volumes, but the precision is the repeated results under unchanged conditions. There are three types of glassware used in analytical lab containers glassware, general glassware, and volumetric glassware1. Volumetric glassware are containers designed to deliver a precise amount of liquid on a specific temperature. For instance, Graduated cylinders, Volumetric flask, Burettes, volumetric pipettes. The Volumetric pipette is a tube with a mark that determines the volume that they are designed to deliver, they are the most accurate pipette 2. Burettes are long-graduated tubes with a stopcock at its base, they are designed to deliver accurately measurable volumes 3 . Erlenmeyer flask is an essential flask in the lab it has a conical base that extends to a small neck 4.But beakers used to hold liquids, and the size of it vary between 10ml and 4000 ml ,it has a lip to help to pour liquids and the volume is not accurate5 .Scientists do the calibration in order to evaluate the precision and the accuracy of the lab equipment 6 .
Water used as a calibrating liquid, the volume of the water calculated from the mass and the density of the water. The concept of Volume is the amount of space a substance occupies (L) and the density of water is the weight of the water depending on the temperature (g/cm^3)7.
