The
Factors that Affect the Rate of Dissolving and Solubility
arthurscience.weebly.com1. The forces holding the solute together must be broken (requires energy) Ionic compounds – the forces holding the ions together must be broken Covalent molecules – the forces holding molecules together must be broken 2. The intermolecular forces (between particles) holding the solvent together must be broken (requires energy) 3.

www.acs.orgintermolecular forces. So when sugar dissolves in water, the attractive forces between the individual molecules are overcome, and these molecules are released into solution. Food-coloring molecules are usually ionic solids, that is, they contain positive and negative ions, which are held together by ionic bonds.
AP Chemistry Scoring Guidelines, 2016
secure-media.collegeboard.orgonly possible intermolecular forces are London dispersion forces. The London dispersion forces are stronger in I because it is larger in size with more electrons and/or a more polarizable electron cloud. The stronger London dispersion forces in I result in a higher melting point,which makes I 2 a solid at room temperature.
