Chemistry Solutions Study Guide

question

Solute
answer

the substance that dissolves, the “dissolvee”, the solute dissolves into the solvent Example: the koolaid powder when koolaid is dissolved into water
question

Solvent
answer

the substance in which the solute dissolves, the “dissolver” Example: the water when koolaid powder is put into it
question

Solution
answer

a homogenous mixture, solute + solvent, solute is smaller than the amount of solvent Types of solutions:
question

Liquid solutions
answer

a gas, solid or liquid dissolved into a liquid Example: cream into coffee, sugar into water, food coloring into water, carbonated water Example: gasses dissolved in one another Example: air, oxygen into air
question

Solid solutions
answer

mixtures of solids Example: Brass
question

Aqueous solution
answer

the solvent is water, water dissolves the solute. Example: NaCl aq, fluids in your body
question

Solubility
answer

a measure of the amount/mass of a substance (solute) that dissolves in a given amount/mass of solvent at a specific temperature
question

Solubility = mass solute (g) / mass solvent (g)
answer

question

Dilute
answer

to make a solution thinner or weaker by adding water or another solvent to it, when a relatively small amount of solute is dissolved in a given amount of solvent Example: Bleach can be diluted by adding water
question

Concentrated
answer

when a relatively large amount of solute is dissolved in a given amount of solvent, a solution with a high amount solute Example: Hot chocolate with 80% powder and 20% milk
question

Saturated
answer

A solution in which the maximum amount of solute is dissolved in a given amount of solvent at a specific temperature (or pressure); “on the curve”, no more solute can be dissolved, the solvent is full Example: Like a paper towel that cannot absorb any more water
question

Unsaturated
answer

a solution in which less than the maximum amount of solute is dissolved in a given amount of solvent at a specific temperature (or pressure), “below the curve”, more solute can be dissolved, the solvent is “not full” Example: a damp paper towel that can absorb more spill
question

Molarity
answer

describes the concentration of a solution how much solute is dissolved the solution; specifically, how many moles solute are dissolved in 1.0 Liter of solution
question

Dilution
answer

the process of making a more dilute solution from a given, more concentrated solution which is called the saturated solution
question

Freezing Point Depression
answer

When solute is added to the solvent and the freezing point of the solution lowers
question

Boiling Point Elevation
answer

When solute is added to the solvent and the boiling point of the solution increases
