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
