The Decomposition of Sodium Hydrogen Carbonate

Aim: the aim of this investigation is to find out the product of decomposition of Sodium Hydrogen Carbonate (NaHCO3).

Hypothesis: we were given three possible products:

  1. Sodium Oxide (Na2o)
  2. (CH3CO2Na)
  3. Sodium Carbonate (Na2CO3)

I predict that the equations that will balance out will be considered a possible product of the reaction. The equations that will not balance out will not be considered a possible product. This is because all equations have to balance out, provided with the correct reactant and products are given. And due to this reason, the equation that will not balance will not be considered a possible product. The equations are the following:

Variables:

Independent: the independent variable is the mass of crucible 

Dependent: the dependent variable in this experiment is the mass of residue.

Controlled:  

  1. The power loss was controlled.  
  2. How long the mixture was heated was controlled.
  3. The mass of the mixture will be constantly measured.
  4. A lid would cover the mixture to minimize power loss.

Apparatus:

  • Bunsen burner
  • Sodium Hydrogen Carbonate
  • Lid
  • Crucible
  •  Tongs
  • Tripod
  • Safety glasses
  • Scale

Method:

  1. The first step would be to collect the apparatus ...
