The solution gradually turned from green to light blue during the addition of the first 3 mL of ethylene diamine solution. It remained light blue until 6 mL when it suddenly became blue.

It remained blue to 12 mL when it suddenly changed to dark blue. It steadily became darker until 17 mL when it suddenly became purple.

A. How many moles of ethylene diamine were added to reach the light blue to blue color change? ________________ mol C2N2H8

How does this compare to the initial moles of NiCl2*6H2O?

Is there excess (unreacted) ethylene diamine or nickel compound?

What is the formula of the nickel containing compound at this point in the reaction?
