Question

1. Fe3+ reacts with SCN- to form FeSCN2+. If 2.0 mL of a 2.3 M solution of Fe3+ is mixed with 2.0 mL of a 0.161 M solution of SCN- and 6.0 mL of water, calculate the concentration of FeSCN2+ in the resulting solution after the reaction completes.

2. Fe3+ reacts with SCN- to form FeSCN2+. If 2.0 mL of 0.493 M Fe3+ are mixed with 2.0 mL of 0.104 M SCN- and 6.0 mL of water, calculate the concentration of leftover Fe3+ in the solution after the reaction completes.
