Chemical Reactions
Essay title: Chemical Reactions
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) Its possible that Solution
