Question 4 Reaction #1 A student combines 100mL. of 0.1M CuCl2 and 50ml of 0.05M AgNO3 The solution is filtered and the solution and solid are separated. Reaction #2 20mL of the remaining solution is combined with 20mL of 0.1M Pb(NOs)2. The solution is filtered and the solution and solid are separated. 1. Write a net ionic equation for the reaction of CuClz with AgNO3. 2. Calculate the mass of solid precipitate produced, if any from the first reaction. 3. Calculate the concentration of Cl in solution at the end of the first reaction 4. Calculate the concentration of Cu2, in solution at the end of the first reaction 5. Calculate the concentration of NOs in solution at the end of the reaction 6. Write a net ionic equation for the reaction of the soluton obtained from filtration after step #1 with Pb(NO3)2 Calculate the mass of precipitate formed in the second step [if any). 7. 8. Calculate the concentration of Cl in solution at the end of the second reaction 9. Calculat 10.
