Purpose: The purpose of this lab is to investigate whether mass is gained or lost during a chemical reaction. Hypothesis: It will be found out that the mass is neither gained nor lost during a chemical reaction but transferred. Materials: * Safety goggles * Erlenmeyer flaskfulful * Balance * Graduated Cylinder * Beaker * cast-iron (III) chloride resolvent * cop (II) sulphate resultant * Sodium bicarbonate * Test pipages (small, and large) * dick Stopper * Tweezers * constitution towel * Scoopula * Sodium hydroxide solution * Hydrochloric acerb Procedure: 1. 5ml of iron (III) chloride was measured and set in the Erlenmeyer flask. 2. The small running play tube was filled center(prenominal) with sodium hydroxide solution and gently placed in the flask without getting melded. 3. The color and clarity of each solution were observed and recorded in the data table. 4. T he outside of the flask was alter with a paper towel. 5. The stopper was firmly devote in the flask. 6. The aggregate mass of the reactants, the run tube and the flask were obdurate victimisation the balance. 7. The flask was gently inverted to mix the solutions together. 8. The reaction was observed and recorded. 9.
The inwardness mass of the products, the test tube and the flask were determined. 10. The test tube was removed from the flask using tweezers and the confine were disposed of in the waste container. The equipments were cleaned and dried for the close use. 11. steps 1-10 were repeated using Copper (II) Sulfate and sodiu! m hydroxide solution Part B: 12. 5 ml of hydrochloric tart was poured into the larger test tube. 13. One scoop of sodium bicarbonate was put into the beaker 14. The test tube was placed in the beaker and the total mass of the reactants, test tube and beaker were determined using the balance. 15. The test tube was removed from the beaker and the acid was poured into the beaker. 16. The...If you want to get a full essay, order it on our website:
