Please EXPLAIN HOW TO calculate the FINAL Fe 3+ ion concentration in equilibrium mixtures E2-E4 amp; explain how to calculate the FINAL SCN- ion…

Please EXPLAIN HOW TO calculate the FINAL Fe 3+ ion concentration in equilibrium mixtures E2-E4 & explain how to calculate the FINAL SCN- ion concentration in equilibrium mixtures E2-E4. Thank you.

you DO NOT need to do the work. I’m just confused on where to start. I calculated the initial concentrations as shown below, but idk where to go from here. Thank you.

Fe^+3

E2 1×10^3

E3 1×10^3

E4 1×10^3

SCN^-

E2 2×10^-4

E3 6×10^-4

E4 1×10^-3

volume of 2 x 10^-3 M Fe(NO3)3 in 1.0 x 10^-1 M HNO3 solution, mL : 50

volume of 2 x 10^-3 M NaSCN in 1.0 x 10^-1 M HNO3 solution, mL : 10

Total solution volume, mL : 100

E3

volume of 2 x 10^-3 M Fe(NO3)3 in 1.0 x 10^-1 M HNO3 solution, mL : 50

volume of 2 x 10^-3 M NaSCN in 1.0 x 10^-1 M HNO3 solution, mL : 30

Total solution volume, mL : 100

E4

volume of 2 x 10^-3 M Fe(NO3)3 in 1.0 x 10^-1 M HNO3 solution, mL : 50

volume of 2 x 10^-3 M NaSCN in 1.0 x 10^-1 M HNO3 solution, mL : 50

Total solution volume, mL : 100
