During the second week, suppose you decide to use volumetric analysis. For each of the unknown compounds on the left, choose the proper titrant (standard solution) and indicator from the drop-down box. There are three indicators for you to choose from: bromothymol blue, phenolphthalein, and methyl orange.

Hints:

HCl is a strong acid;

NaOH is a strong base;

CH3COONa, Na2C2O4 are basic salts that form weak bases in aqueous solutions;

NH4Cl is an acidic salt that forms weak acid in an aqueous solution.

CH3COONa

[ Choose ] HCl, methyl orange NaOH, phenolphthalein HCl, phenolphthalein, and then methyl orange HCl, bromothymol blue

Na2CO3

[ Choose ] HCl, methyl orange NaOH, phenolphthalein HCl, phenolphthalein, and then methyl orange HCl, bromothymol blue

Na2C2O4

[ Choose ] HCl, methyl orange NaOH, phenolphthalein HCl, phenolphthalein, and then methyl orange HCl, bromothymol blue

NH4Cl

[ Choose ] HCl, methyl orange NaOH, phenolphthalein HCl, phenolphthalein, and then methyl orange HCl, bromothymol blue

NaOH

[ Choose ] HCl, methyl orange NaOH, phenolphthalein HCl, phenolphthalein, and then methyl orange HCl, bromothymol blue
