Question

1. Using a graduated cylinder to measure volumes, combine 3.0 mL of 0.10 M AgNO, with 3.0 ml of 1.0 M NH3 in a 15 x 150 mm test tube. Swirl to combine and set aside. 2. Prepare 0.02 M NaCI. Pour 0.1 M NaCl into a graduated cylinder to the 2-mL mark. Record the exact volume to two decimal places. Add water to the 10-mL mark. Mix thoroughly and record the exact volume to two decimal places. Calculate the exact concentration using M 3. Using a disposable pipet, add about 1 mL of the NaCl solution from step 2 to the solution in the test tube (step 1). Continue adding the dilute NaCI solution dropwise until a faint but constant 1V1-M2V2 precipitate of AgCI forms. Return any excess NaCI in the pipet to the graduated cylinder. 5. Record the final volume in the graduated cylinder. Calculate the exact volume of NaCI solution 4. used Equilibrium constant of the ammonia complex ion. E. Write an equation for the formation of the complex ion. 1. 2. Calculate the concentrations of Ag', NH3, and Ag(NHs)2' at equilibrium. 3. Write an equilibrium constant expression for the formation reaction. Calculate the equilibrium constant. 4.

Assuming 5mL of NaCl solution is used, what will be equilibrium constant? Please provide explanation for steps.
Thank you!
