Question

you have 3 unlabelled test tubes containing ethanol,ethanol acid and soap solution.Explain the method you use to identity the compounds in different test tubes by chemical tests using litmus paper and sodium metal

Answer 1

Blue litmus paper turns red when in contact with acid. So ethanoic acid will turn the blue litmus paper red.
​Red litmus paper turns blue when in contact with base. So soap solution will turn the red litmus paper blue.
Ethanol when reacted with sodium metal gives off hydrogen gas bubbles that confirms its presence.
 

Answer 2

Ethanoic acid will turn blue litmus to red

Ethanoic will liberate H2 gas with Na

Soap solution will turn red litmus to blue
