5 TEACHER RESOURCE PAGE dissolves. The ions, already present, separate from one another. Ionization is the process of forming ions from the solute molecules by the action of the solvent. When a molecular compound dissolves and ionizes in a polar solvent, ions are formed. 21. In a strong electrolyte, all or almost all of the dissolved compound exists as ions in aqueous solution. In a weak electrolyte, little of the dissolved compound exists as ions in aqueous solution. 22. When a compound containing hydrogen dissolves in water to form a hydrogen ion, H, the H ion attracts other molecules or ions so strongly that it rarely exists alone. In water, the H ion immediately bonds to a water molecule, forming a hydronium ion, H 3 O. 23. Dissolved salt will lower the freezing point of water. Therefore, adding salt to icy roads will help melt the ice and prevent further freezing of any water on the road s surface. It will also prevent the refreezing of water as it melts. 24. none 25.
