Question

Circle the ion(s) indicated in each of the following. This worksheet includes ions that are not in your experimental procedure. a. A white salt was soluble in water. Addition of hydrochloric acid formed a colorless, odorless gas. SO_4^2- NO_3^- CO_3^2- Cl^- Br^- I^- NH_4^+ b. A salt was treated with NaOH solution. A gas, which turned red litmus blue, was produced. Na^+ NH_4^+ Ag^+ Fe^3- Al^3+ Li^+ Ca^2+ Mg^2+ K^+ Zn^2+ Hg_2^2+ c. A salt was soluble in water. Addition of hydrochloric acid formed a white precipitate. Na^+ NH_4^+ Ag^+ Fe^3- Al^3+ Li^+ Ca^2+ Mg^2+ K^+ Zn^2+ Hg_2^2+ c d. The pH of a solution was raised, with NaOH, to about 10. A precipitate formed. Na^+ NH_4^+ Ag^+ Fe^3- Al^3+ Li^+ Mg^2+ K^+ Zn^2+ Hg_2^2+ c Would there be any solid present when a sample containing lead(II) nitrate, sodium carbonate, and calcium chloride is mixed with water? List the formula(s) for all solids present (if any). A sample consists of one or more of these salts: ammonium nitrate, sodium sulfide, potassium carbonate, lead(II) acetate. The sample dissolves completely in water. When a sodium sulfate is added, a precipitate forms. Write the correct formulas for your responses. The term "might" means that the salt may, or may not, be present. Which of the salts must be present in the sample? _____ Which of the salts might be present in the sample? _____ Which of the salts must be absent in the sample? _____ A sample consists of one or more of these salts: sodium acetate, potassium chloride, lead(ll) nitrate, calcium carbonate. The sample dissolves completely in water. A precipitate forms when aqueous KI is added. Write the correct formulas for each of your responses. Which of the salts must be present in the sample? _____ Which of the salts might be present in the sample? _____ Which of the salts must be absent in the sample? _____ A sample consists of one or more of these salts: ammonium nitrate, ammonium bromide, calcium nitrate, silver nitrate, lead(II) nitrate. The sample dissolves completely in water. When cold dilute HCl is added, a white precipitate forms which is filtered off and found to be completely soluble in hot water. To the filtrate, ammonium carbonate solution is added and a white precipitate forms. Heating the original sample with NaOH solution gives a gas that turns moist red litmus blue and has a pungent odor write the correct formulas for each of your responses. Which of the salts must be present in the sample? _____ Which of the salts might be present in the sample? _____ Which of the salts must be absent in the sample? _____

Explanation / Answer

Qualitative analysis:

1)a) CO3- -

   b) NH4+

c)Ag+

d)Fe3+

2) PbCl2 is insoluble in water

3)PbSO4 must be present in water as insoluble salt.

4)Precipitate formed is of PbI2

5)    AgNO3+HCl         --------->     AgCl (ppt.)   + HNO3

   2AgCl + (NH4)2CO3 -------> Ag2CO3 + 2 NH4Cl

     (NH4)2CO3 + 2NaOH Heat         -------> 2NH3 (g) + Na2CO3 + 2H2O
