Question

1. below is a representation of the solvation process (e.g., water dissolving a sugar crystal): when one compound dissolves into another, is it a physical or chemical change? explain.

Explanation:

In a physical change, the substance's chemical composition remains the same. When a compound dissolves in another (solvation), no new substances are formed. The solute and solvent retain their chemical identities. For example, when sugar dissolves in water, it is still sugar and water at the molecular level, just mixed together. In a chemical change, new substances with different chemical properties are formed through chemical reactions. Since dissolution doesn't create new substances, it is a physical change.

Answer:

It is a physical change. The chemical identities of the solute and solvent remain unchanged during the dissolution process, and no new substances are formed.
