Through the method of gravimetric analysis, the results showed that the baking
soda is in fact impure. The substance is in fact 94.8% baking soda, with 5.2% being
impurities. The initial mass of the baking soda and the crucible is 17.622g. After h
Sodium bicarbonate (NaHC), more commonly known as baking soda, is a natural

Part A- Standardization of a Hydrochloric Acid Solution
1. Prepare a 150 mL solution of 0.6M hydrochloric acid solution from HCl.
2. Add about 1.5 grams of NaCO to a 250mL beaker. Add enough distilled water to the
beaker to dissolve the NaCO.
