Distinguish between types of solutions such as electrolytes and nonelectrolytes, saturated, and supersaturated solutions. Describe the unique role of water in chemical and biological systems. How do outside factors such as pressure and temperature influence solutions in our everyday lives? Investigate factors that influence solubility and rates of dissolution such as temperature, agitation and surface area. Develop and use general rules for solubility through investigations with aqueous solutions. Calculate the concentration of solutions in units of molarity (moles/Liters) and use molarity to calculate the dilutions of solutions.

What does it mean that “like dissolves like”? Explain what a hydrogen bond is and how it gives water its unique properties. What affects the rate of dissolution of solids and gases in water? Explain how large bodies of water are able to moderate air temperature? How do outside factors such as pressure and temperature influence solutions in our everyday life? How do you determine if an ionic compound is soluble in water? Distinguish between types of solutions such as electrolytes and non-electrolytes. Calculate the concentration of a 3 liter solution containing 3 g of NaCl. How many mL of a 12 M HCl solution are required to make a 500 mL solution that has a 0.5 M HCl concentration? Predict the solubility of a substance at different temperatures using a solubility graph. Determine if a solution is unsaturated, saturated, or supersaturated using a solubility graph.
