Animal Costumes Halloween Costumes Kids halloween costumes kids Information


Purpose: 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
