what is solution?

Hi,
 
A true solution is the solution in which solute particles are homogeneously mixed to form a single phase solution.
It is a clear and transparent solution which can easily pass through ordinary filter paper or animal membrane. Its particles are not visible.
 
Hope it helps.
Cheers!

A SOLUTION IS THE MIXTURE OF A SOLUTE AND A SOLVENT.

THUMBS UP PLZZZ..

 A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.

 

  • solvent: the substance in which a solute dissolves to produce a homogeneous mixture
  • solute: the substance that dissolves in a solvent to produce a homogeneous mixture

Note that the solvent is the substance that is present in the greatest amount.

Many different kinds of solutions exist. For example, a solute can be a gas, a liquid or a solid. Solvents can also be gases, liquids or solids.

The following figures show the microscopic behavior of several different kinds of solutions. Note that in each case, the solute particles are uniformly distributed among the solvent particles.

 A solution is a mixture of one substance dissolved in another so the properties are the same throughout. A solution is composed of a solute and the solvent. The solute is the substance being dissolved and the solvent is the part of the solution that does the dissolving. The solute is of molecular size.

Examples of Solutions:

  
GasLiquidSolid
 GasOxygen and other gases in nitrogen (air)
Water vapor in air (humidity)		The odor of a solid -- molecules of that solid being dissolved in the air
LiquidCarbon dioxide in water (carbonated water)Ethanol (common alcohol) in water; various hydrocarbons in each other (petroleum) *Sucrose (table sugar) in water; sodium chloride (table salt) in water
SolidHydrogen dissolved to palladiumWater in activated charcoalSteel, Brass, other metal alloys

* Two liquids that are soluble are said to be miscible in one another.

 

Strength of Solutions

The solubility is the amount of solute that be be dissolved in a given amount of solvent at any one temperature. A solution is said to be unsaturated as long as more solute can be dissolved.

Dilute or Weak Solution - only a small amount of solute compared to solvent.

Concentrated Solution - A relatively large amount of solute to solvent.

Saturated Solution --At this point, the concentration of the solute in solution is the maximum possible under the existing conditions (temperature and pressure). A solution is saturated when no more solute can be dissolved at the current temperature. A saturated solution is one in which the dissolved and undissolved solutes are in equilibrium.

Supersaturated Solution -- a solution that contains more dissolved substance than does a saturated solution; the solution is not in equilibrium with the pure substance. Examples of supersaturated solutions are carbonated water,
