Flour is a white solid that burns and does not dissolve in water. Sugar is a white solid that dissolves in water and will turn brown and give off a sweet odor when heated. A student finds an unlabeled container in the kitchen that is either flour or sugar. Describe a procedure that they could follow to identify the substance and explain how the student could use the properties of the substance to identify it. (Science)

See explanation

Explanation:

A simple test that will distinguish flour from sugar is to dissolve the unknown substance in water.

Sugar dissolves in water due to the presence of polar groups in the chemical structure of sugar that are capable of interaction with water.

Flour does not dissolve in water. It rather becomes suspended in water when agitated and settles at the bottom of the container when the suspension is left to stand.
