When you mix a solid and a liquid together, the solid usually either dissolves or separates from the liquid. For solutions of gases in liquids, we can safely ignore the energy required to separate the solute molecules (\(H_2 = 0\)) because the molecules are already separated. When substances are combined, they may form a mixture, in which the individual substances retain their chemical properties, or they may form a chemical reaction, in which a new substance with its own chemical properties is created. In contrast, water-soluble vitamins, such as vitamin C, are polar, hydrophilic molecules that circulate in the blood and intracellular fluids, which are primarily aqueous. What property of the unknown substance was the chemist most likely investigating?

Name Why would nonmetals be unlikely to have the type of bonding shown here? What is another name for the dimethylbenzenes? The fact that the solubilities decrease as the lattice energy increases suggests that the \(H_2\) term in Figure 13.1 dominates for this series of compounds. A true solution will settle out after a short period of time. The amount of heat released is proportional to the amount of solute that exceeds its solubility. Substances that dissolve in water are called soluble substances. The resources below have been grouped as follows: A homogeneous mixture is one in which the composition of the mixture is uniform throughout. Table 2: Solubility data for NH4Cl in water.
