TEMPERATURE
What is a solute?
This is the substance that dissolves in a solution.
Water and oil do not mix because their molecules differ in this property.
polarity
The phenomenon where the boiling point of a solvent increases when a nonvolatile solute is added is called this.
boiling point elevation
This laboratory device is used to heat substances using an open flame.
Bunsen burner
This heating device is used as an alternative to a Bunsen burner, especially for gently heating substances.
hot plate
What is solubility?
This term refers to the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.
A solution that can still dissolve more solute at a given temperature is called this.
unsaturated solution
This piece of glassware is used to measure the volume of liquids accurately and has markings along its length.
graduated cylinder
This instrument magnifies small objects using light and lenses.
microscope
his triangular piece of heat-resistant material is used to support a crucible over a flame.
clay triangle
This term refers to two liquids that can mix in any proportion without separating.
miscibility
A solution holding more solute than it normally can at a given temperature is called this, and is often unstable.
supersaturated solution
This tool is used to hold test tubes, especially when heating them over a flame.
test tube holder
This is used to accurately measure and transfer very small volumes of liquid.
pipet
This tall, graduated piece of glassware is used for delivering precise volumes of liquid in titration experiments.
buret
Increasing this factor generally increases the solubility of most solids in liquids but decreases the solubility of gases in liquids.
temperature
This factor, referring to the size of solute particles, generally decreases solubility when increased.
molecular size
This colligative property describes the pressure required to prevent solvent molecules from moving through a semipermeable membrane.
osmotic pressure
This type of glassware is shaped like a cone with a flat bottom, making it ideal for mixing without spilling.
Erlenmeyer flask
This small tool is used to transfer small amounts of liquid drop by drop.
dropper
Adding salt to water lowers this property, which is why it’s used to melt ice on roads.
freezing point depression
The pressure exerted by a vapor in equilibrium with its liquid is called this.
vapor pressure
When a solute is added to a solvent, this property always decreases, explaining why sugar water evaporates more slowly than pure water.
vapor pressure lowering
This glassware tool has a narrow stem and is used to guide liquids into containers with small openings.
glass funnel
This metal tool is used to pick up and hold hot containers such as beakers or crucibles.
