1001. How can you speed up the process of dissolution? — T
Dissolution occurs when a solid material is disassembled into its constituent atoms, molecules, or ions and these particles are carried around in a solvent liquid. Since the disassembly is a statistical process, with thermal energy allowing particles to leave the solid and chance allowing them occasionally to return to the solid again, anything you can do to accelerate the leaving process and impede the returning process will speed dissolution. Heating the solid and liquid will speed dissolution by making it easier for particles to leave the solid and harder for them to stick when they try to return. Keeping fresh, pure solvent in contact with the solid will also prevent molecules from returning.
