Wedding birthday supplies.Wedding birthday supplies InformationPurpose: To understand how single displacement and double displacement theories apply to real life situations. Procedure: See Pg. 244-245. Observations: Experiment Results a)sodium chloride + silver nitrate milky/blue/white later turned gray b)silver nitrate + potassium iodide white/yellow(clear well) blue/green(black well) c)iron(III) chloride + sodium hydroxide Apple Juice Yellow d)sodium chloride + potassium nitrate No visible change e)sodium carbonate + calcium chloride Turned Milky Conclusion: Analysis a-e) See table under Observations. g) Evidence was shown in the experiment through the colour change in the solutions. All the solutions except Solution D reacted. h) Errors could be caused by mixing up unlabelled breakers, overfilling the wells, and otherwise contaminating the solutions so their results were not accurate. i) It\'s possible that Solution D reacted to such a small magnitude, that it was not visible. Therefore, I cannot conclude that it did not react. Understanding Concepts 1.a) A double displacement reaction is when two molecules on each side of the equation switch places in a chemical reaction. b) A single displacement reaction is when one molecule on each side of the equation switch places in a chemical reaction. 2. See table under Observations. 3-5. a) NaCl + AuNO3 --> NaNO3 + AuCl b) AuNO3 + KI --> AuI + KNO3 c) Fe3Cl + NaOH --> Fe3OH + NaCl d) NaCl + KNO3 --> NaNO3 + KCl e) NaCO3 + CaCl --> CaCO3 + NaCl |
