Answer 1

Answer:

6. There are two ways to tell the difference between salt and sugar without tasting either one of them. One way is to place them separately in separate pans, and cook them. Sugar has a higher boiling point than does salt. When heated sugar will melt into a brown syrupy sustains Salt will not melt. Another way is to pour them on a slug. Salt melts the skin of the slug, but sugar does not.

Slug means Lichen,(an organism). But I'll suggest not to do so why to kill an organism just to know whether it is sugar or salt..
