1.)
Preparation of a Standard Solution
Purpose: This is a skill-based lab create
a standard solution of certain concentration of a copper (II)
sulfate pentahydrate.
Prelab: Calculate the mass of
CuSO­4(aq) need to prepare 100.00 mL of 0.500mol/L
of solution.
Round your answer to three significant
digits.
2.)
Preparation of a Standard Solution by
Dilution
Purpose: Prepare a standard solution by
diluting a stock solution.
Prelab: Calculate the volume of a
0.500mol/L stock solution of CuSO­4(aq) required to
prepare 100 mL of 0.0500mol/L solution.
Round your answer to three significant
figures.
UNITS: mL
