1. Using Excel, generate titration curves for your strong acid-strong base titration and your
weak acid-strong base titration. Be sure the graphs are properly formatted with correct axes
labels, appropriate axes scales, descriptive titles, and the appropriate extrapolation lines.
Copy and paste the graphs into a word document ( make sure the extrapolation lines
have not moved) then save the document as a PDF. Submit this PDF on ECLearn along
with your complete worksheet.
2. Calculate the concentration of your strong acid, HCl unknown #2. Show all work. Be sure to
show the extrapolation of the equivalence point on your graph.
