| the easyest ways i can think of would be smell and maybe specific gravity. Assuming the additive is easy to detect.

| Depending on the additive it may show up in an IR.

| Checking the boiling point might work. Pure substances boil at lower temperatures than mixtures.

also u can use the hydrometer to measure its density.
it will be different.
