How would I do it ?
In my primitive way. Get some Sugar and some Salt and some of the unknown substance and sprinkle it on each of 3 ice cubes.
the one with salt (or 2 with salt) will melt faster then the one with sugar (or 2 with sugar).
Does that make any sense ?

Sugar will melt at a much lower temperature than salt.

I'd dissolve both in water (separately, of course) and measure the electrical conductivity/resistance with a volt-ohmmeter. The salt solution will have a greatly reduced resistance.

A sugar is made up of solely carbons, oxygens and hydrogens. Salts are made with other elements in addition to those.

You can evaporate the water and look at the precipitate left behind under a microscope.
