Question

I have atttched the lab we completed in class and the post lab as well. I need help completeting the post lab.

Lab Worksheet Unknown Number Record your careful observations in this table. Use your observations and logical inference to the unknowns AgNO, test BaCl; test Anion silver nitrate nitric acid barium cbloride hydrochloric acid /?.UPI chloride ?? k bromide iodide sulfate carbonate rarly sotd phosphate hvdroxide odl acetate 50 Unknown A Unknown B I believe Unknown A contains the anion ulta because: I believe Unknown B contains the anion Chlor:de because Qualitative Analysis

Explanation / Answer

1. AgNO3 or BaCl2 both form presipitate with all the other anions except for acetate and thus If by adding the two reagent we do not observe any precipitate in solution. Then we have acetate as the anion present in solution.

2. Balanced equations,

a. AgNO3 + NaCl --> AgCl(ppt) + NaNO3

b. AgNO3 + NaBr --> AgBr(ppt) + NaNO3

c. AgNO3 + NaI --> AgI(ppt) + NaNO3

d. 2AgNO3 + Na2SO4 --> Ag2SO4(ppt) + 2NaNO3

e. 2AgNO3 + Na2CO3 --> Ag2CO3(ppt) + 2NaNO3

f. 3AgNO3 + Na3PO4 ---> Ag3PO4(ppt) + 3NaNO3

g. AgNO3 + NaOH ---> AgOH(ppt) + NaNO3

h. AgNO3 + NaC2H3O2 ---> AgC2H3O2 + NaNO3
