PRE-LAB QUESTIONS:
Using calculations AND words, explain how you would prepare the following solutions for this lab (show all your work – think about conversion factors):
A) A 1.0 L stock solution of 0.10 M AgNO3(aq) from solid AgNO3.
(molar mass of AgNO3 = 169.9 g/mol).
B XXXXXXXXXXmL of 0.25 M H2SO4 from a 1.0 M H2SO4 stock solution.
C) 150 mL of a 5% (mass/volume) solution of K2CrO4 from solid K2CrO4.
D) A group of students perform their first titration for this lab and find that they needed
28.5 mL of XXXXXXXXXXM AgNO3(aq) to reach the end point. Based on this information,
What is the concentration of Cl- ions.
