High School Chemistry
Mass balance in chemical reactions
Lead (II) nitrate and potassium iodide solutions are placed in a conical flask on an electronic balance. The two solutions are not in contact.
A rubber bung is inserted into the mouth of the flask making a closed system and the mass on the balance recorded.
When the two solutions inside the flask are allowed to mix, a chemical reaction occurs.
The mass of the reacting system is recorded.
In a closed system such as the flask in this experiment, no matter can enter the flask and none escapes.
Students are asked if there is an overall mass change when a chemical reaction takes place in a closed system.
