    1. Thank you for taking a moment to reply to the question. Your are correct that one pile is salt and the other is sugar. But… it is the other way around: left sugar and right salt. It is not so easy to tell in this photo but if you could see the individual crystals more closely you might discern the salt crystals are little cubes while the sugar ones are a more elongated shape. Check out this reference:
