Purpose: To find what substances are produced in a chemical reaction.
Procedure: Refer to 3-3C Observing changes in matter
Changes made include:
Reactants Strontium Chloride and Sodium Carbonate
Flame Test uses solid powders on innoculation loop
Amount of Strontium Chloride and Sodium Carbonate changed from 25ml to 10ml
Data and Observations:
Strontium Chloride: Clear, liquid
Sodium Carbonate: Clear, liquid
Observations of Changes:
When the liquids were combined they became an opaque liquid. When we put the liquid through a filter we were left with a white powder in the filter and a clear liquid.
Sodium Carbonate: The flame turned orange
Strontium Chloride: The flame turned red
Product of reaction: The flame turned orange
Analysis:
When we mixed the two liquids it caused a chemical change. The chemical change caused Strontium Chloride and Sodium Carbonate to change into Sodium Chloride and Strontium Carbonate.
Conclusion:
Using my results I can determine that the substances that were produced from the chemical change are Sodium Chloride and Strontium Carbonate. When we filtered the two substances, the Sodium Chloride was a solid powder, while the Strontium Carbonate was the liquid. I can determine this from the results of the flame test. The flame test results show that sodium turns flames orange and strontium turns flames red. When we put the solid powder in our filter through the flame the flame turned orange. This means that the powder is sodium chloride and the liquid is strontium carbonate.
