A volume of 40.0 mL of Iron (II) Sulfate is oxidized to Iron (III) by 20.0 mL of 0.100 M Potassium dichromate solution. What is the concentration of the Iron (III) Sulfate Solution?

Thank you for the opportunity to help you with your question!

This is a classic chemistry problem that deals with Molarity.

Just use this equation M1V1 = M2V2

M1 is molarity for the potassium dichromate = 0.100M

V1 is the volume of original Iron (II) sulfate before oxidation = 40.0 mL

V2 is the final volume after the Iron(II) sulfate is oxidized to Iron (III) by 20 ml Potassium dichromate. So the

final volume is 40ml + 20ml = 60 ml

Solve for M2

M2 = M1V1/V2

= (0.100M) ( 40 ml) / 60 ml

= 4 M ml/ 60 ml

= 0.067 M

Thank you for your time and this helped tremendiously.
