There are many ways by which we can differentiate between sugar and salt without testing not be dissolved.

1) Heat these salts separately, sugar will melt readily while salt will not.

• WHERE SUGAR MELTS AND TURNS BLACKISH
• AND SALT DOES NOT ( IT DOEST NOT MELT)

2) Dissolve these two separately in water. Salt solution will conduct electricity due to the presence of Na+ ion and Cl− while sugar solution will be a non-conductor. So, simply test a drop of the solution with an ohmmeter and you can immediately tell the difference.
