I'm currently in high school doing a project in chemistry. So I had to make a project where concepts from physical chemistry will be used alongside organic chemistry.
After going through my book I decided to create a test for carboxylic acids using electrochemistry. The basis of the test is:
Aldehydes, ketones and alcohols are non ionic in aqueous solution while carboxylic acids are ionic. Therefore carboxylic acid can be used as an electrolyte.
So I finalized the following:
Lead, copper (my school doesn't have much chemicals and reagents and mostly available one was lead and copper so I stuck with it). The thing is, boiling the given organic compound with elemental lead, hydrogen peroxide and taking the precipitate obtained and measure the weight and dissolve it in test tube with water this acts as an electrolyte for lead half cell and make a copper half cell and connect the copper electrode and lead electrode with wires and put a suitable salt bridge. If there is reading in ammeter connected to the wires then the given organic compound contains carboxylic acid.
Is my method okay? Edit:
1)since someone pointed out a lot of flaws , can I do like this: Taking the aqueos solution of the organic compound as electrolyte and putting Zn,Cu electrodes in it and connecting the electrodes using a wire and connecting the wires to an ammeter ,(will this work like a lemon battery?)
