1) A lab technician adds 3.50 mL of a 0.00450 M stock solution of barium chloride to a test tube, then adds other solutions so that the total volume is 10.00 mL.
What is the molarity of the barium ions? What about the molarity of the chloride ions?
2) A solution initially contains 0.00100 M Fe3+ ion and 0.00080 M SCN- ion, and the concentration of FeSCN2+ at equilibrium is measured to be 0.000125 M.
What is the value of the equilibrium concentration for the iron(III) ion?
What is the value of the equilibrium constant?
