Part Two

Determine the concentration of an HCl solution via a titration with 0.100 M

NaOH. Here HCl is the analyte and NaOH is the titrant. Each laboratory partner

should successfully complete one titration of the HCl solution following the

general steps on the previous page. Use a 25.00 mL volumetric pipet to add the

analyte to the Erlenmeyer flask. Check that your laboratory partner does the

following when completing their titration:

•Is analyte added to flask with volumetric pipet?

•Is indicator added to the flask?

•Is the initial volume of buret recorded to 2 decimal places in notebook?

•Does the solution turn color with the addition of one drop or less of

titrant solution?

•Is the final volume of buret recorded to 2 decimal places?

•Is waste solution appropriately disposed of?
