Equillibrium Question (concentrations)
« on: March 23, 2015, 08:57:18 PM »
Fe3+(aq)  +  SCN-(aq)  ::equil::  FeSCN2+(aq)

1. A solution is created by adding 3 ml of a 0.002M solution of KSCN to 2ml of distilled water and 5 ml of a 0.002M solution of Fe(NO3)3. What is the concentration of SCN- ions in the solution?

2.   What is the concentration of Fe3+ ions in the solution formed in question 1?

3.   A solution is created by adding 2mL of a 0.00200M solution of KSCN to 18 mL of a 0.200M solution of Fe(NO3)3.  What is the concentration of SCN- ions in the solution?

4.   What is the concentration of Fe3+ ions in the solution formed in question 3?

5.   Using the solution that was made in question 3, which reactant would be the limiting reagent if the reaction is
Fe3+(aq)  +  SCN-(aq)  ::equil::  FeSCN2+(aq)

6.   Assuming the reaction goes to completion, what would be the concentration of FeSCN2+ produced?

I'm so stuck on all of them please help
