1. In a small beaker mix together 5.0 mL of 0.10 M Co(NO3)2 . 6H2O with 5.0 mL of concentrated HCl. Be sure to mix thoroughly with your glass stirring rod. This is your equilibrium mixture. 2. Place 1.0 mL of your equilibrium mixture in a small test tube add 1.0 mL of concentrated HCl. Observe any color changes and state in which direction (if any) the equilibrium shifted. Place a new 1.0 mL sample of your equilibrium mixture in...

I don't understand what calculations I would have made to create
the buffer solution from Part D of the lab. I understood the
procedures I took to create the solution but when the report asks
to show the calculations used to prepare the buffer solution I am
not sure other than mixing the volumes indicated in the procedures
section.
