Experiment 2- Post Lab, # 3,4,& 6 Samiya Channe 3. What would be observed (and why) from an aqueous mixture for each of the following: a. Potassium Carbonate and Hydrochloric Acid K2CO3 + 2HCl 2KCl +H2CO3 We get potassium chloride and carbonic acid. What we would observe would be no precipitate in this reaction as HCl and KCl are highly soluble and form aqueous ions. b. Zinc Chloride and silver nitrate ZnCl2 + 2AgNO3 Zn(NO3)2+2AgCl No precipitate will form because these are both soluble.

Unformatted text preview: c. Magnesium Chloride and sodium hydroxide MgCl2 + 2NaOH MgOH2 + 2NaCl The solution would acquire a milky color and a precipitate would form. d. Ammonium nitrate and sodium hydroxide NH4NO3 + NaOH NaNO3 + NH4OH We will observe and odor of ammonia and a colorless gas 4. a. 1= HCl-solution 2 = Na2CO3-solution 3 = AgNO3-solution b. If added 1 to 3 = AgCl would precipitate. HCl + AgNO3 ---> AgCl + HNO3 6. T1. HCL T2. KOH T3. Na2CO3...
