solutes
what is a solute
A solute is a substance that is dissolved in a solvent to form a solution.
what is a solvent?
a substance usually a liquid.
what is a solution?
a solution is a homogenious mixture of two or more substances uniformly dispersed at a molecular or iconic level consisting of a solute
what is a pure substance.
what is the main mixture?
the main mixture in life is air
what is the solute in saltwater?
salt
how does temperature affect solvents?
increasing the kinetic energy of molecules.
what are the four types of solutions?
* solid in a liquid
*liquid in a liquid
* gas in a liquid
*gas in a gas
what are two types of pure substances?
element and compound
what is an everyday solute people use mostly adults
coffee
is a solute always always a solid?
no a solute is not always a solid.
why do some substances dissolve in certain solvents while others do not.
substances dissolve based on the principal of "like dissolves like"
can a solution be a solid?
yes. a solution can be a solid.
how is a pure substance different from a mixture?
a pure substance cannot be separated physically, where as mixtures can.
what is a mixture?
two or more substances physically put together but not chemically bonded.
what mixture does a solute and solvent make?
a solution.
what is a polar solvent?
a liquid that dissolves polar or iconic substances by having molecules with large dipole moments-uneven electrical charge distribution and high dielectric constants.
what is a supersaturated solution?
a chemical mixture that contains the maximum amount of solute. (substance) dissolved in a solvent (liquid) at a specific tempeture.
is distilled water a pure substance?
yes it consists only of h2o molecules.
what is a heterogeneous mixture?
a combination of two or more substances that are not uniformallly distributed and can be visually distinguished.
what is the universal solute?
the solvent that dissolves many solutes.
why is water called the universal solvent?
this refers to its ability to dissolve a wider variety of substances compared to other liquids.
what defines a true solution?
a true solution is a homogenious mixture where a solute particles are fully dissolved in a solvent,with particles sizes smaller than 1 nm and 10-9m
while pure water is a compound, why is it considered a pure substance rather than a mixture?
it consists only of one type of molecule (H20)
what is a homogenious mixture?
a solid, liquid, or gases mixture that's has the same uniform composition and appearance throughout
