Chemistry

  1. Show calculations and briefly describe how you will makethe following solutions:

    1. 50.00 mL of 0.200 M Fe(NO3)3(aq) solution from iron(III)nitrate nonahydrate

    2. 200.00 mL of a 2.00 mM KSCN(aq) solution from potassiumthiocyanate.

    3. 100.00 mL of 1.00 M CoCl2(aq) solution from cobalt(II)chloride hexahydrate.

  2. Write the equilibrium expression for parts A, B, and Cof the lab based on the equations that are shown in the priorsection.

  3. Look at the expression for cobalt complexation withchloride ions (Part B of the lab). How would doubling the amount ofwater in the reaction vessel affect the product concentrationscompared to the reactant concentrations?

  4. How is the [ ] used in metal complexes like the cobalttetrachloride complex [CoCl4]2- different from the [ ] used in thegeneral equilibrium expression that follows?

K=[B]2[C]/[A
