Report - Chemicals In Everyday Life (6pts) Chemicals in EverydayLife How will you collect data for this experiment? virtually A.Household Ammonia, NH4OH Effect of household ammonia on dry litmusno change, stays red Effect of household ammonia on moist litmuschanges to blue Effect of NH4Cl on litmus no change, stays redEffect of NH4Cl + NaOH on litmus changes to blue Effect offertilizer + NaOH on litmus changes to blue Effect of smellingsalts, (NH4)2CO3, on litmus changes to blue B. Baking Soda, NaHCO3Effect of adding H2SO4 to baking soda bubbles, gas formation Effectof adding vinegar to baking soda bubbles, gas formation Observationof Ba(OH)2 drop above HCl and chalk reaction bubbles, gas formationC. Table Salt, NaCl Effect of adding H2SO4 to table salt on bluelitmus paper turns litmus red Effect of adding AgNO3 on table saltsolution white ppt forms Effect of adding AgNO3 on tap water whiteppt forms Observation of salt in flame yellow flame D. Epsom Salts,MgSO4·7H2O Effect of adding H2SO4 to Epsom salts no reaction Effectof adding BaCl2 to Epsom salt solution solution becomes cloudy E.Bleach, NaOCl Effect of adding bleach to NaI solution mineral oilis reddish-brown Effect of adding AgNO3 to NaI solution pale yellowppt Effect of adding H2SO4 to NaI solution turns dark brownsolution, fumes, and rotten egg smell F. Unknown Enter your unknownnumber 27 (14pts) Analysis Use the observations above to answer thefollowing questions about chemicals you tested. A. HouseholdAmmonia, NH4OH (2/2pts) Based on your observation in Part A withthe effect of fertilizer + NaOH on litmus, does fertilizer containammonia? yes check_circle (2/2pts) Based on your observation inPart A with the effect of smelling salts on litmus, do smellingsalts contain ammonia? yes check_circle B. Baking Soda, NaHCO3(2/2pts) Based on your observation in Part B with the Ba(OH)2 drop,does chalk contain carbonate ion? yes check_circle C. Table Salt,NaCl (pending/2pts) Complete and balance the reaction betweensulfuric acid and sodium chloride H2SO4(aq) + 2NaCl(s) → 2HCl (aq)+ Na2SO4(aq) (pending/2pts) Why should you used distilled ordeionized water instead of tap water when using AgNO3 as a test foranions? (2/2pts) Based on your observation in Part C with addingAgNO3 to tap water, does tap water contain chloride ion? yescheck_circle E. Bleach, NaOCl (pending/2pts) Complete and balancethe reaction between silver nitrate and sodium iodide solutions.AgNO3(aq) + NaI(aq) → NaNO3(aq) + Agl(s) (13pts) Part F. UnknownAnalysis Your given unknown contains one of four anions (carbonate,chloride, iodide, or sulfate). To identify the anion present, youfirst carried out the H2SO4 test. You observed the following whenaddding H2SO4 to your unknown: no observable reaction (1/1pts)Which option best matches your observations for the H2SO4 test onyour unknown? No change observed check_circle (0/2pts) Based onyour observations, which ion do you suspect is present in yourunknown? chloride highlight_off (-2 pts) Incorrect. That is not theion indicated by the results of the sulfuric acid test (0/2pts)Which confirmatory test is appropriate for your unknown? bariumchloride solution highlight_off (-2 pts) Incorrect. This is not thecorrect test based on the ion you suspect to be present in yourunknown. You observed white precipitate from the barium chlorideconfirmatory test carried out on your unknown. (1/1pts) Which ofthe following options best matches your observations for theconfirmatory test on your unknown? white ppt check_circle (0/5pts)Based on the results of the H2SO4 test and the confimatory test,what anion does your unknown contain? chloride highlight_off (-5pts) Incorrect. That is not the correct anion for the unknowngiven. (pending/2pts) Summarize your results and explain yourreasoning for the identification of the anion in yourunknown.
