Question

I am trying to figure out how to find the initial concentrations to start filling out one of these ICE tables. I don't need you to do all the tables, but please show me how to finish one because I am so confused right now! If you help me I will rate your answer a thumbs up. Thank
you!

all the data needed should be found in the first table with the mL amounts of the solutions.

Explanation / Answer

Following are the calculations for beaker B:

Final volume of mixture in beaker = 10 mL

Stock conc. of Fe3+ used = 0.0020 M

Volume of this stock solution used = 3 mL

Let's represent the reaction taking place by the following equation:

Fe3+ + SCN- ----> FeSCN2+.

Since final volume is 10 mL, it corresponds to a dilution by a factor of 10/3.

So initial conc of Fe3+ in the beaker comes: 0.002/(10/3) = 0.0006 M

Stock conc. of SCN- used = 0.0020 M

Volume of this stock solution used = 4 mL

Since final volume is 10 mL, it corresponds to a dilution by a factor of 10/4.

So initial conc of SCN- in the beaker comes: 0.002/(10/4) = 0.0008 M

Let's represent the reaction taking place by the following equation:

Fe3+ + SCN- ----> FeSCN2+
