1. If the standard solutions had unknowingly been made up tobe 0.0024 M AgNO3 and 0.0040 M K2CrO4, would this have affected your results? Why?

2. If your curvette had been dirty, how would this have affected the value of ksp?

3. Using your determined value of ksp, calculate how manymilligrams of Ag2CrO4 will desolve in 10.0 mL of H2O?

4. The experimental procedure for this experiment has you add 5mL of 0.004 M AgNO3 to 5mL of 0.0024 M K2CrO4. Is either of these reagents in excess, if so which one?

5. Use your experimentally determined value of ksp and show,by calculations, that Ag2CrO4 should precipitate when 5mL of 0.004M AgNO3 are added to 5mL of 0.0024 M K2CrO4.
