Solvents, Solutes, and Solutions Flashcard

What is a solution?
A homogeneous mixture; consists of solutes dissolved in a solvent.
What is the difference between a solute and a solvent?
A solute is what is dissolved in a solution. For example, chocolate syrup. A solvent is what the solute dissolves in. For example, Milk. Creating a solution of: Chocolate Milk.
What is the difference between saturated, unsaturated, and supersaturated?
Saturated- Contains the maximum amount of solvent a for a solution. Unsaturated-Contans the lowest amount of solute possible. Supersaturated- A solution contains more solute than possible.
What is the difference between dilute and concentrated?
Dilute- It contains a smaller amount of solute in relation to the solvent. Concentration- Contains a larger amount of solute in relation to the solvent.
What 3 factors affect the rate in which a substance dissolves? How do these factors affect the rate of dissolution?
Temperature-Warmer means faster. Agitation- Stirring increases dissolving. Surface Area- Smaller area is easier to heat or stir.
What factors affect the rate of solubility? How do these factors affect the rate of solubility?
Temperature and Pressure.
How can the solubility of a solution be written?
Grams of solute OVER 1 liter of solvent. Grams of solute OVER one hundred grams of solvent.
What is a polar molecule?
A nonpolar molecule?
Polar- has a positive side and a negative side.
Nonpolar-Electrons are shared 2 atoms.
What is an emulsifier?
A dispersion of a liquid in a liquid.
How does an emulsifier work?
Grease and Oil aren’t soluble with water, so soap connects them.
Give two examples of emulsifiers.
Milk and Soap.
How do you find dilutions?
M1V1 = M2V2
How is Henry’s law written? Solubility and Pressure.
What is a suspension? What is a colloid? Give an example of each.
Suspension- a mixture from which some of the particles settle out upon standing. Like a snowglobe.
Colloid- Mixture where particles are intermediate in size between those of a suspension an a solute. Like gel.
How do solutions differ from suspensions and colloids?
Solutions are homogeneous.
What is the Tyndall effect? What substances exhibit the Tyndall effect?
The scattering of light throughout a substance. Colloid and Suspension.
