Hardness of Water

Lab Report for Hardness of Water



(title page)

Introduction…as usual…state the purpose and explain the chemistry involved…do NOT just list all the calculations in the intro

Data: simply use lab computer print-out…be sure to attach it in the data section (NOT AT END)

Calculations: show all the calculations…there were 7 titrations…so show 7 equations and 7 calculations and 7 answers…be sure to give the equation used, use labels, units and proper significant figures.

Discussion: State the ppm results for the water samples (tap and unknown) for the 2 methods. Compare to the actual given values and compare the 2 methods to each other. % error is a good way to compare the 4 results. Comment on accuracy and precision. Discuss sources of experimental error.
