Stoichiometry Reaction Lab
Title:
Stoichiometry Reaction
Objectives:
1. To decompose sodium hydrogen carbonate (sodium bicarbonate) by heating.
2. To accurately measure the degree of completion of the reaction by analysing the solid sodium carbonate product.
3. To calculate amount of product with given amount of reactant.
4. To determine amount of heat release in the reaction.
Results:
Part 1: Thermal Decomposition of NaHCO3
Materials Mass (g)
Clean and dry test tube 15.1632
Clean test tube + NaHCO3 17.1647
Amount of NaHCO3 added 2.0015
After heated test tube + NaHCO3 16.4500
Amount of solid product (NaHCO3 + any unreacted NaHCO3) 1.2868
Part 2: Titration of Na2CO3 with Hydrochloric acid (HCl) First Reading Second Reading Third Reading
