Fe(NO3)3+KSCN ---- FeSCN^2+KNO3

the assumption was made that all of the SCN^- which had been added to the standard solutions had been converted to FeSCN^2+.

Is this assumption reasonable. Explain considering the initial concentration of SCN- relative to that of Fe3+ in each sample

soln	0.200M Fe(NO3)3 (ml)	0.00200M KSCN (ml)	water (ml)	FeSCN2+ (ml)
1	5.00	0.20	4.80	4x10^-5
2	5.00	0.40	4.60	8x10^-5
3	5.00	0.60	4.40	1.2x10^-4
4	5.00	0.80	4.20	1.6x10^-4
5	5.00	1.00	4.00	2.00x10-4
