$3 Name: Pre-Lab Questions - Lab 5 Show calculations and/or answer questions will complete sentences, where applicable. Answer questions 1-2 based upon this solution: Solution A was produced by dissolving 7.98 milligrams solid iron(III) thiocyanate nonahydrate in enough water to produce a 100.00 mL solution. 1) What is the concentration, in millimolarity, of Fe(SCN)3 in solution A? 2) A second solution, solutions B, was produced by adding 50.00 mL of deionized water to 20.00 mL of solution A. What is the concentration, in millimolarity, of Fe(SCN), in the diluted solution? (assume the volumes are additive) 3) Describe the laboratory technique of serial dilutions. 4) The step by step procedure for this lab have not been described in the lab manual. In this lab you have been provided the general overview of the lab, experimental guidelines and a description on how to use the spectrometer. In the space below (or on a separate sheet or digitally), write out a detailed experimental flow chart for the procedure you will complete in lab.

Pre-Lab Questions - Lab 5
Show calculations and/or answer questions will complete sentences, where applicable.
Answer questions 1-2 based upon this solution:
Solution A was produced by dissolving 7.98 milligrams solid iron(III) thiocyanate
nonahydrate in enough water to produce a 100.00 mL solution.
1) What is the concentration, in millimolarity, of Fe(SCN)3 in solution A?
2) A second solution, solutions B, was produced by adding 50.00 mL of deionized water to
20.00 mL of solution A. What is the concentration, in millimolarity, of Fe(SCN), in the
diluted solution? (assume the volumes are additive)
3) Describe the laboratory technique of serial dilutions.
4) The step by step procedure for this lab have not been described in the lab manual. In this
lab you have been provided the general overview of the lab, experimental guidelines and
a description on how to use the spectrometer. In the space below (or on a separate sheet
or digitally), write out a detailed experimental flow chart for the procedure you will
complete in lab. The more detailed this flow chart, the easier your time in lab will be
designing your experimental procedure. You will be able to use this flowchart during the
lab.
