Data Section:
Attach the following three pages to this Lab Report:
1.
Your Solution B plot shows both your data and class data, with trendlines and equations
2.
A plot showing the class data for both Solution A and Solution B, with trendlines and equations for each.
3.
A table of calculated and fit densities from your spreadsheet showing your density values for both Solution A and
Solution B determined using different methods: calculated average from your data, graphical method with your data,
and graphical method with class data.
Results Section:
Interpret your data and discuss the results by answering the following questions.
1.
Do any of the data points for Solutions A or B disagree significantly with the rest of the class data?
If so, note that here and circle these points on the plot.
Density (g/mL)
Solution A
Solution B
Calculated
0.922 g/mL
.886 g/mL
My best fit
0.921 g/mL
0.886 g/mL
Class Data
0.951 g/mL
0.877 g/mL
2.
Compare your density for Solution A determined by the averaging and graphical method.
How well do they agree?
They do not agree. The Class data density is significantly higher than the calculated density for
Solution A. My data stand curve line for solution A is more precise than the calculated density
for Solution A.
3.
Compare your density for Solution B determined by the averaging and graphical method.
How well do they agree?
Class data density is significantly higher than the calculated density. But the calculated density is
accurate to my data density.
4.
Compare your densities for Solution A with the class value.
How well do they agree?
According to Solution A, my data is more significant than the class data. I know so because my
data R
2
is closer to 1 than the class data R
2.
5.
Compare your densities for Solution B with the class value.
How well do they agree?
According to Solution B, class data seems to be more significant than my data. I know so because
class data R
2
is closer to 1 than my data.
6.
Compare the class densities for Solutions A and B.
Are they the same?
Based on this result, are
Solutions A and B the same?
Explain why.

Instructions You are required to produce a short lab report using the information given in the accompanying document, ‘Lab report assessment_student data’. This document introduces an experiment, and also provides a set of experimental data for this experiment. You are required to use this data to perform steps 8 and 9 of the procedure. This includes calculations of a particular value, and then comparison to the true value. Consider any experimental errors when comparing calculated values and true values. Your report should be between 300 and 500 words (including all table contents and titles of tables and graphs). Your lab report should consist of three sections only: • Experimental • Results and Discussion • Conclusion You do NOT need to include an introduction section. Your experimental section should be written in appropriate lab report format, (passive voice, 3 rd person, in paragraphs). Your results and discussion section should contain the data presented in table format, and…

V. Error Analysis/Questions For the following questions explain what specific error in calculating your Ksp value would occur (i.e. would the Ksp be too HIGH or too LOW), compared to the situation in which no errors occur. When you answer the question, consider how the situation affects the calculation of Ksp. Each answer must have an explanation and type the answer, please.
A. The buret was not conditioned (it still had water in it) when you add the HCl. Would the Ksp be too HIGH or too LOW?
B. There was Ca(OH)2 solid (that was not filtered off) in your solution to be titrated. Would the Ksp be too HIGH or too LOW?
C. You measured 24.00 mL of Ca(OH)2 solution instead of 25.00 mL. Would the Ksp be too HIGH or too LOW?
D. The HCl concentration was actually lower than the reported molarity on the bottle. Would the Ksp be too HIGH or too LOW?
