what are the particles that dissolve in a solvent
Solute and solvent. A solute is the substance that dissolves to make a solution. In salt solution, salt is the solute. A solvent is the substance that does the dissolving â it dissolves the solute. In salt solution, water is the solvent. During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.
