Chapter 7 Solutions Flashcards
What is a colloid?
A mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions that are suspended in a solid, liquid, or gas
What is emulsion?
Any mixture of two or more immiscible liquids in which one liquid is dispersed in the other
What is a solution?
A homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
What is a solute?
In a solution, the substance that dissolves in the solvent
What is a solvent?
In a solution, the substance in which the solute dissolves
What is an alloy?
A solid or liquid mixture of two or more metals
What is a heterogeneous mixture?
a mixture that composes of components that aren’t uniform or they have localized regions that all have different properties.
What is decanting?
Gradually pouring one substance into another
What is immiscible?
When a substance does not mix well with another
What is the Tyndall effect?
light scattering by particles in a colloid or else particles in a very fine suspension.
What is a polar compound?
A molecule that has an uneven distribution of electrons
What is hydrogen bonding?
The intermolecular force occurring when a hydrogen atom that is bonded to a highly electro-negative atom of one molecule is attracted to two unshared electrons of another molecule
What are nonpolar compounds?
A compound whose electrons are equally distributed among its atoms
What is solubility?
The maximum amount of a solute that will dissolve in a given quantity of solvent at a given temperature and pressure
What is concentration?
The amount of a particular substance in a given quantity of a mixture, solute, or ore
