Question

A 10.00 mL chloride sample required 33.65 mL of 0.01251 M AgNO_3 to reach the end point. a) How many moles of CI^- were present in the sample? b) What was the molarity of the CI^- sample? Would the following errors increase, decrease or not change the molarity of CI^- as calculated is part lb? Explain your answer (use a calculation if needed)! a) The student was past the end point of the titration when final volume was recorded. b) The student incorrectly read the molarity of AgNO_3 as 0.01521 M

Explanation / Answer

Q2

a.

past the end point tiration of th efinal volume recorded...

if we get past the endpoint, this means we have excess titrant

if we relate mol of titrant = mol of specie

then we are accounting EXTRA

meaning we are actually miscalculating, we have a larger amount than that really is

i.e. it is higher
