What would you observe in an evaporating dish after evaporating distilled water to dryness?

When you evaporate distilled water in an evaporating dish until it reaches dryness, you would not observe any solid residue left in the dish. Distilled water is purified water that has been boiled to vapor and then condensed back into liquid, removing any impurities or dissolved solids. As a result, when this water evaporates, it transforms into vapor and leaves no trace behind.

However, if the dish was not perfectly clean or if there were any initial impurities in the water, you might see some residue, which would be the contaminants that didn’t evaporate. In essence, pure distilled water, when evaporated completely, should leave behind a clean and dry surface in the evaporating dish.
