Question

Match the following limit test reagents correctly.

A) Arsenic	1) Dithizone
B) Lead	2) Thioglycolic acid
C) Iron	3) Barium chloride
D) Barium	4) Mercuric chloride

• A. A-4; B-1; C-2; D-3
• B. A-3; B-2; C-4; D-1
• C. A-2; B-1; C-4; D-3
• D. A-3; B-4; C-2; D-1

Hint:

Matching reagents to their respective limit tests is key in analytical chemistry. Use mnemonics or tables for quick recall.

Answer 1

The Correct Option is A

Each metal ion has a specific reagent used in its limit test: - Arsenic is tested using mercuric chloride. - Lead is tested using dithizone. - Iron is detected with thioglycolic acid. - Barium is identified using barium chloride in the test.
