Chemistry "Solutions"

When are Solutions formed?

Solutions are formed when two or more substances mix completely together to form homogeneous mixture

Characteristics

•Have one face

•Possess the same properties throughout their parts

•Have one state

Solute

The substance that dissolves in another. It is the minor component.

Solvent

The substance which the solute dissolves in. It is the major component

Types of Solutions

•Solid solution

•Liquid solution:

Acquoes solution “solvent is water”

Non-acquies solution “solvent is not water”

•Gasous solution

Dilute Solution

Solution is one in which there is a relatively small amount of solute dissolved in the solution

Concentrated Solution

A concentrated solution contains a relatively large amount of solute

What is Concentration?

Concentration is the amount of solute divided by the total volume of a mixture

Concentration=

Mass of solute/Volume of solvent

Unites of concentration

g/L-g/ml-g/cm3

Characteristics of diluted solutions

•Has very little solute in it

•Can dissolve a lot more solute

Characteristics of concentrated solutions

•Has a lot of solute in it

•Can dissolve a little more solute

Characteristics of saturated Solutions

•Has the maximum amount of solute in it

•Cannot dissolve any more solute

How to change from diluted to concentrated solution? “What happens to the color”

The Solution’s color gets darker

•add more solutes

•remove solvent by evaporation or boiling

How to change from concentrated to diluted solution? “What happens to the color”

The Solution's color gets lighter

•add more solvent

Concentration increase means mass…

Increase

Volume increase means concentration…

Decrease

Concentration increase means volume…

Decreases

Mass decrease means concentration…

Decrease
