Question 5: To verify the existence of Yu2 in your solution, one should first form a white precipitate by addition of NaCl. Next, the precipitate should dissolve with the addition of NaOH. Using chemical equations, describe the identity of the product formed in each step. (Your two steps should be after the addition of NaCl and after the addition of NaOH). I Question 6: To verify the existence of Rb in your solution, one should first form a white precipitate by addition of NaCl. Next, the precipitate should dissolve with the addition of NH,. Using chemical equations, descrive the identity of the product formed in each step. (Your two steps should be after the addition of NaCl and after the addition of NH). Question 7: Yu can form a precipitate and/or complex ion when it is mixed with sodium chloride depending on the concentration of chloride ions present in solution a) Write the reaction for the formation of the precipitate and the reaction for the formation of the complex ion. b) What concentration of Cl' is required to form a precipitate of YuCl (s)? ([Yu]=0.12 M; [NaCl] = 3.0 M). Your answer should be listed as molar concentration. c) What concentration of Cl is required to form a complex ion of (YuC1,2} (aq), whose concentration is 0.24 M? Assume the concentration of [Yu] is 0.12 M. Your answer should be listed as molar concentration.
