Question

five different salts each imparted a yellow color to a flame and reacted with cold H2SO4 as follows. identify each salt.

A. effercescence was observed, and the evolved gas was colorless and odorless and did not fume in moist air.

B. effervescence was observed, and the evolved gas was pale reddish-brown, had a sharp odor, and fumed strongly in moist air.

C. no effervescence was observed, and the evolved gas was colorless, had a sharp odor, and fumed in moist air.

D. effervescence was observed, and the evolved gas was colorless, had a sharp odor, and fumed in moist air.

E. effervescence was observed, and the evolved colorless gas had a very sharp odor but did not fume in moist air and did not discolor a piece of filter paper that had been moistened with a solution of lead acetate.

Explanation / Answer

yellow colour due to Na+ ion present in all the salts.

so cation of all salts is Na+

a. for the first salt anion may be CO32-

b. for the second salt anion may be Br-

c. for the third salt anion may be CH3COO-

d. for the fourth salt anion may be SO32-

e. for the fifth salt anion may be Cl-
