Double Displacement Reaction Experiment: Chemistry 1121, Lab Reports of Chemistry

Baton Rouge Community CollegeChemistry

An experiment on double displacement reactions, focusing on the reaction between sodium sulfate and barium chloride. The experiment aims to classify the reaction type and observe the formation of barium sulfate precipitates. The procedure involves mixing the solutions, observing the precipitate formation, and testing its solubility in hydrochloric acid. The experiment concludes that the reaction is a double displacement reaction, where sulfate ions are displaced by chloride ions, resulting in the formation of barium sulfate and sodium chloride. This experiment provides a practical understanding of double displacement reactions and the formation of precipitates, enhancing students' comprehension of chemical reactions and their applications in chemistry.

ABSTRACT:

  1. The goals of this experiment is to study the reaction between sodium sulfate and barium chloride and classify it as combination, decomposition, single displacement or double displacement reaction.
  2. The reaction was carried out by following procedure: https://www.youtube.com/watch?v=kgMARnXlmBY

Chemicals:

Name Chemical Formula Hazard Sodium Sulfate Na 2 SO 4 May case eye and skin irritation. Causes nausea, vomiting and diarrhea. Barium chloride BaCl 2 Irritates the eyes, skin, and mucous membranes.

Barium chloride may affect the kidneys, cardiovascular system, and central nervous system. Hydrogen chloride HCl Causes skin irritation and serious eye damage. Causes respiratory damage if inhaled.

Chemical Reactions:

The following double displacement chemical reaction was demonstrated in this experiment: Na 2 SO 4 (aq) + BaCl 2 (aq) → BaSO 4 + 2NaCl (^) (aq)

Procedure:

  1. Added the small amount of sodium sulfate solution in a boiling tube.
  2. Added small amount of barium chloride solution in another boiling tube.
  3. Poured the barium chloride solution in tube containing sodium sulfate solution.
  4. Placed the tube undisturbed for 10 minutes.
  5. After the white precipitates settled down, decanted the solution into beaker.
  6. Added few drops of dilute HCl into the white precipitates.
  7. Shake the test tube well.
