									                                    Decomposition of Sodium Bicarbonate
Background and Purpose:

       Sodium bicarbonate (sodium hydrogen carbonate) decomposes at around 50oC. One of the products of
the decomposition is carbon dioxide, which makes baking soda a popular ingredient in baking. Why would the
production of carbon dioxide make it popular?

A.) When baking soda (sodium bicarbonate) is heated, it decomposes to gaseous carbon dioxide and solid
sodium hydroxide.
B.) When baking soda (sodium bicarbonate) is heated, it decomposes to gaseous carbon dioxide, water vapor
and solid sodium oxide.
C.) When baking soda (sodium bicarbonate) is heated, it decomposes to gaseous carbon dioxide, water vapor,
and solid sodium carbonate.

In the lab, determine the correct equation.

Equipment: Crucible, Baking Soda, Balance, Crucible tong, scoopula, burner, ring stand, ring and clay triangle.

Conclusion: Explain how you determined the correct equation in a TYPED conclusion.
       Things to discuss: possible reactions, how you performed the lab, what is the correct decomposition
equation and why!
