A) Compute the initial concentrations of SCN- and Fe3+ ions while a solution was prepared by mixing 3mL of 0.00280 M KSCN, 6mL of 0.250 M Fe(NO3)3, as well as 16mL of 0.050 M HNO3. Note- the total final volume of this solution is 25mL

B) If you assume the reaction is driven to completion for the reason of the large excess of one ion define what is the concentration of [Fe(SCN)]2+ that would be formed?

Fe3+ (aq) + SCN-(aq) <----> [Fe(SCN)]2+ (aq)
