Results
The basics:
Mass of ________ used = _.____g
Volume of ________ used = _____cm3
(Or just Quantity of ________ used = Appropriate SF/DP unit)
Recording for graph:
1.
Initial burette reading /cm3
Final burette reading /cm3
Volume of _____ used/collected/etc /cm3
2.
Time /min/sec Temperature/Other quantities /oC
Comment:
1) There are no anomalous results as data points for the experiment fall close to or on their respective line/curve of best-fit. All points fall within a 5% difference in dependent variable difference, ie. __ small squares from the graph drawn.
2) The lack of anomaly could be due to the care taken to ensure that the readings were taken at the correct timings/or some other reason.
VS.
1) There are anomalous results as some/one of the points fall out of the trend of the ________ graph at independent variable value = ____ units. The point is more than 5% difference in dependent variable different, ie. __ small squares from the graph drawn.
2) There could have been inconsistent swirling resulting in inaccurate measurement of the temperature.
Lastly:
3) If time permits, the whole experiment should be repeated again.
Calculations
Evaluation of Experiment
1) State Sources of error
2) State Impact on results
a. How it affects immediate results
b. How it affects final results
3) State Suggested Improvements
