Homework Help: reagents

Posted by Chloe on Monday, October 9, 2006 at 6:44pm.

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.

Hi! Very nice site! Thanks you very much! KFvDxlGrexZ8

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.
