As we saw in Section 91 Solutions this means that substances must have similar intermolecular forces to form solutions. In molecular nature similar solute molecules are. How Does A Solute Dissolve In A Solvent Solutions Chemistry Don T Memorise Youtube How would you describe the dissolving process at the moleculer level by using the concept of random molecular motion. . The concept of dissolving is when a solid called a solute completely mixes with a liquid called a solvent at the molecular level to become a single visible phase and become a homogeneous mixture. As the copper ions dissolve into the water they form a coordination complex with salts already present. Dissolving needs another term to be used this is solvation. Students see that a liquids ability to dissolve a substance is a characteristic property that can be used to identify the liquid. The solvent particles must move apart to make room for solute particles. ...
