Chemical Properties of Water
What is the term that describes the unequal sharing of electrons in water molecules?
What is polarity?
What is another name for dissolved ions and can conduct electricity?
What is an electrolyte?
How does temperature generally affect the solubility of solid solutes?
What is increasing temperature usually increases solubility?
Describe the difference between a concentrated versus dilute solution.
What is a concentrated solution contains more solute than a dilute solution?
How do you dilute a solution?
What is to decrease the concentration by adding more solvent?
Why is water known as the "universal solvent"?
What is its ability to dissolve many substances due to its polarity?
Define a nonelectrolyte solution.
What is a solution that does not conduct electricity due to the absence of ions?
Describe how agitation affects the rate of dissolution.
What is agitation increases the rate of dissolution by allowing more solute to come into contact with the solvent?
What unit is commonly used to express concentration in chemistry?
What is molarity?
What formula is used for calculating dilutions?
What is C₁V₁ = C₂V₂?
Describe what temporary dipoles are.
What are temporary charges positive and negative charges that induce polarity in a molecule.
What is the difference between a saturated and an unsaturated solution?
What is a saturated solution contains the maximum amount of solute, while an unsaturated solution can still dissolve more solute?
What is the relationship between surface area and solubility?
What is a larger surface area increases the rate of dissolution?
What is the formula for calculating molarity?
What is Molarity (M) = moles of solute / liters of solution?
How would you prepare 500 mL of a 0.5 M solution from a 2 M stock solution?
What is find V1 from the following calculation ((500 mL)(0.5 M))/(2 M) = 125 mL of V1. You would take 125 mL of the 2 M solution and add it to a new beaker, then subtract the 125 mL from 500 mL to find that you need to add 375 mL of water to make the 0.5 M solution.
Describe how water's polarity contributes to its ability to form solutions.
What is it allows water molecules to surround and interact with polar and ionic compounds?
What are supersaturated solutions?
What are solutions that contain more solute than can typically dissolve at a given temperature?
Explain how a solubility curve can be used to determine the saturation point of a solution.
What is it shows the maximum amount of solute that can dissolve at various temperatures?
How would you calculate the molarity of a solution containing 0.5 moles of solute in 0.25 liters?
What is 0.5 mol/0.25 L = 2 M?
What is the molarity of a solution if 3 grams of NaCl are dissolved in 0.5 liters of water?
What is approximately 0.1 M?
