WebAug 19, 2024 · A student was titrating 25.00 mL of a basic solution with an HCl solution that was 0.281 M. The student ran out of the HCl solution after having added 32.46 mL, so she borrowed an HCl solution that was labeled as 0.317 M. An additional 11.5 mL of the second solution was needed to complete the titration.

WebFor best results, a titration should require 20-40 mL of titrant. If your mixture has very little KHP in it, you may need to use up to 2 g of sample, so that more titrant will be required. Do not use more than 2 g, or we will run out. Do at least 3 titrations with the same size sample. Calculate how many moles of KHP are present in your sample.
