1. What are the experimental uncertainties in preparing a stock solution?
2. What are the experimental uncertainties in preparing a solution by diluting a stock
solution?
3. What is the effect of temperature on the accuracy of the concentrations? Why?
4. Compare your conductivity values for 6.4.1 and 6.4.3. What causes the difference?
5. How do your solutions' concentrations compare with the ones determined from your
conductivity measurements? If there is a discrepancy, what might have caused it?
6. Compare your conductivity values for 6.4.1 (NaCl solution) and 6.4.4 (CH,COOH
solution). What causes the difference?
