Do these reagents fit with the substance being testd for?
First is Biuret reagent protein
Second is BACL^2 starch
Third is AgNO^3 chloride ion
Final is albustix protein.
I can help with two of these.
BaCl2 is used to test for sulfates, not starch.
AgNO3 is used to test for the chloride ion.
Biuret is a test for protein.
Albustix is a test for protein.
This question is written badly. The reagent is the item on the left and the test is written after it Bacl2 as is written above is a test for sulfites and not starch so this is the one that does not belong.
