The purpose of this experiment is to determine the percent composition of carbon in a sample of sodium bicarbonate, NaHCO3. Reacting sodium bicarbonate with sulfuric acid will release carbon in the form of carbon dioxide. According to the Law of Definite Proportions, the mass percentage of carbon in the bicarbonate will be constant, no matter how much sodium bicarbonate is used in the experiment. You will be determining the percent composition of carbon in sodium carbonate, both…
By observing reactions between single elements and compounds, scientists have been able to determine a list of elements in order of their activity. In this experiment, you will observe many different chemical reactions, and you will construct your own list of elements in order of their activity.
This is a very simple, but very reliable lab that introduces the mole concept. Purpose: To understand the meaning of the term "mole" and to enable students to gain a better understanding as to the size of a mole. $2.25
