Solute Vs Solvent: What’s The Difference? - Science Trends

Web15 de set. de 2024 · The answer depends in part on the solute, but there are some similarities common to all solutes. Recall the rule that like dissolves like. This means that substances must have similar intermolecular forces to form solutions. When a soluble solute is introduced into a solvent, the particles of solute can interact with the particles of solvent.
