Reference no: EM13224872

1) The observations listed were made on different solns. Given the observations state which ion studied in this experiment is present. If the test is not definitive, indicate that with a (?).

a) Addition of 6 M NaOH and Al to the soln produces a vapor that turns red litmus blue.

b) Adding 6 M HCl produces a vapor with an acrid odor.

c) Adding 6 M HCl produces an effervescence.

d) Adding 6 M HNO3 plus 0.1 M AgNO3 produces a precipitate.

e) Adding of 6 M HNO3 plus 1 M BaCl2 produces a precipitate.

f) Adding of 6 M HNO3 plus 0.5 M (NH4)2MoO4 produces a precipitate.

2) An unknown containing one or more of the ions studied in this experiment has these properties:

a) No effect on addition of 6 M HNO3

b) No effect on addition of 0.1 M AgNO3 to soln in Part A.

c) White precipitate on addition of 1 M BaCl2 to soln in Part A.

d) Yellow precipitate on addition of (NH4)2MoO4 to soln in Part

On the basis of this information which ions are present, which are absent, and which are in doubt?
