Purpose:

To observe a chemical reaction and to use qualitative and quantitative evidence to identify this reaction from among four possibilities.
Apparatus:
Ignition test tube Retort stand Crucible tongs
Single hole stopper Iron ring Safety goggles
Rubber tubing Wire gauze Flint lighter
Bunsen burner Evaporating dish Hot pad
Wooden splint Small test tube Crucible
Test tube clamp Electronic balance

Materials: 2.0g of Sodium hydrogen carbonate (NaHCO3) Limewater (Ca(OH)2) Cobalt chloride paper (CoCl2)
Introduction:

Baking soda will be heated in a decomposition reactions and one of the following reactions will occur. Using your quantitative and qualitative results, you will choose the correct equation for the reaction that occurs from these 4 equations.

NaHCO3(s) → NaOH(s) + CO2(g) (1)

2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) (2) √ 2NaHCO3(s) → Na2O(s) + 2CO2(g) + H2O(g) (3)

2NaHCO3(s) → 2Na2C2O4(s) + O2(g) + 2H2O(g) (4)
The analysis is split into two parts, A and B. Part A is for qualitative observations and its purpose is to find any water concentration using
