Describes liquids that are insoluble in one another | Immiscible |
Solution containing maximum amount of solute | Saturated Solution |
Solution containing more solute than can theoretically dissolve at a given temperature | Supersaturated Solution |
At a given temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. | Henry's Law |
Measure of the amount of solute dissolved in a specified quantity of solvent | Concentration |
Number of moles of solute dissolved in 1 L of solution | Molarity |
A colligative property related to the fact that ice will form at higher temperatures in the Great Lakes than in the ocean | Freezing Point Depression (FPD) |
A colligative property related to a decrease in the vapor pressure of a solution | Boiling Point Elevation (BPE) |
Number of moles of solute dissolved in 1 kg of solvent | molality |
ratio of moles of solute in solution to total number of moles of both solvent and solute | mole fraction |
How do you dilute a solution? | add more solvent (usually water) |
How would you change a saturated solution to an unsaturated one? | add more solvent (usually water) |
How do you calculate molarity? | molarity(M)= moles of solute/liter of solution |
What are the colligative properties of a solution? | vapor pressure depression, freezing point depression, and boiling point elevation |
Ocean water is very salty. What will this do to freezing point and boiling point (evaporation)? | oceans will freeze at lower temperatures and evaporate more slowly |
What factors influence the solubility of a substance> | Temperature for all solutes and pressure of the gas solutes |
What are the units for solubility? | grams solute/100 grams solvent |
Why do only nonvolatile solutes cause the elevation of boiling point? | at high temperatures, only nonvolatile solutes remain in solution |
What describes the effect of pressure on solubility of a gas in a liquid? | it's directly proportional to the pressure of the gas just above the liquid |
What is the units for molarity? | molarity(M)= moles of solute/liter of solution |
What is molaity units? | molaity(m)= mole of solute/ kg of solution |
