Solution

Solution

 A solution is homogeneous mixture of two or more chemically non-reacting substances whose composition can be varied change) within certain limits

The solutions contained two components-

1. Solute 
2. Solvent 

• The solution contained only two-component (solute & solvent) is called Binary solution.
• The solution containing three and four-component is called Ternary and Quaternary solution. 
• The solution in water is called as an aqueous solution 
• the solution in any other solvent like benzene; ether etc is called a Non-aqueous solution

Type of Solutions

 Depending upon the physical state of solute and solvent, the solution can be classified into nine types of S.No. Solute Solvent Type of solution Examples Alloys
S.No.  Solute   Solvent  Type of solution   Example
1.        Solid     Solid      Solid in Solid       Alloys
2.        Liquid   Solid      Liquid in Solid     Hydrated salt
3.        Gas       Solid      Gas in Solid          Gases in minerals
4.        Solid     Liquid    Solid in liquid       Sugar in water
5.        Liquid   Liquid    Liquid in Liquid   Alcohol in water
6.        Gas        Liquid-  Gas in liquid         Aerated drinks, O2 in water
7.        Solid     Gas         Solid in Gas         Camphor in air, iodine vapor in the air
8         liquid    Gas         Liquid in GAs      Moisture in the air
9         Gas       Gas         Gas in Gas            Air (O2+ N2)
1. The percent by weight (w/w): It is the amount of solute in grams present in 100 g of the solution. 2. The percent by volume (w/v): For Solid salute, it is the amount of solute in grams present in 100 ml of the solution For Liquid solute (v/v), it is the amount of solute in m present in 100 ml of the solution.
3. Strength: It is the amount of solute in grams present in one liter (or dm3) of the solution
