 * 6.05 ** Investigate and analyze the properties and composition of solutions:
 * Give examples of solutions containing solutes and solvents of various phases such as alloys and carbonated drinks.
 * Explain the polar nature of water (The phrase “like dissolves like” is often used to explain why substance dissolves another which is an over simplification of the process).
 * Investigate the factors that affect the rate of solution of a solid including concentration, stirring, temperature, and surface area.
 * Compare and contrast electrical conductivity of solutions containing ionic and covalent solutes.
 * Interpret the solubility curves for solids (concentration vs temperature). Investigate various concentrations unsaturated through supersaturated.
 * Conduct an experiment to illustrate trends in solubility.
 * Identify the acid, base, and salt in a neutralization reaction. (See 6.03)
 * Compare and contrast the physical and chemical characteristics of acids, bases, and neutral substances.
 * Develop an understanding of the concentration of ions in the organization of the pH scale.
 * Investigate the pH of various substances using various indicators: litmus paper, phenolphthalein, and pH paper.
