**Determining Initial and Equilibrium Concentration (Help!)**

## Homework Statement

You are given the equation Fe

^{3+}+ SCN

^{-}-> FeSCN

^{-}

You are performing an experiment in which you are mixing Fe(NO

_{3})

_{3}and NaSCN. A table is given and I will only list the first sets of data because if i can figure out the process for the first one I can figure out the rest. The table is:

10 mL of 2.0x10

^{-3}M Fe(NO

^{3})

_{3}

2mL of 2.0x10

^{-3}

Total Volume of Solution: 50mL

You are asked to to calculate the initial SCN

^{-}concentration (M) as well as the equilibrium FeNCS

^{2+}concentration (M)

I am just not sure how to go about doing that. Any help would be greatly appreciated!

NOTE: It also mentions that to assume all of the SCN

^{-}is present as FeNCS

^{2+}but I am pretty sure that this is irrelevant and is relevant to the later part of the lab
