Solution

Solution 

              A homogeneous mixture of two or more substances is said to be solution. These substances are classified as Solvent and Solute. The solution in which there are two substances is said to be binary solution. One solvent and other is solute.
All binary solutions are solution but all solutions are not binary.Solution are classified as the following solution which are as follow

1. Solid
2. Liquid
3. Gasseous

         The solution in which solid is as solvent and solid, liquid and gas anyone of these is as a solute is said to be solid solution.There are following types of solid solution

• Solid to Solid

• Solid to Liquid

• Solid to Gas

       The solution in which liquid is as solvent and solid, liquid and gas anyone of these is as a solute is said to liquid solution.There are following types of liquid solution

• Liquid to Solid

• Liquid to Liquid

• Liquid to Gas

     The solution in which gas is as solvent and solid, liquid and gas anyone of these is as a solute is said to gaseous solution.There are following types of gaseous solution

• Gas to Solid

• Gas to Liquid

• Gas to Gas

  Aqueous or Aqueous Solution

        The solution in which water is used as solvent is said to be aqueous solution

Non aqueous Solution

        The solution in which water is not used as solvent is said to be Non aqueous solution.

The amount of solute dissolved in a solvent.

 As per, there are following types of solution

• Unsaturated

• Saturated

• Supersaturated

Unsaturated

               The solution in which more solute can be dissolved without rising temperature is said to be unsaturated solution. 

Saturated 

              The solution in which more solute cannot be dissolved further at a given temperature is said to be saturated solution. 

Supersaturated

            The solution in which having more solute than that would be necessary to saturate it at given temperature is said to be Supersaturated.

Matter Surrounding Us

Matter

Anythings which have both mass and volume is said to be matter or occupy space and have mass.

Air, Gas, Water, Stone, Clouds, Stars, Plants and Animals, Food stuffs etcetera are the examples of matter.

Early Indian philoshgers classified matter in the form of five basic elements the Panch Tatva 

which are

1. Air
2. Earth
3. Water
4. Fire 
5. Sky

According to them everything, living or non-living, was made of these five basic elements.

As per Modern Age, classification of matter based on Physical Properties and Chemical Nature of matter.

As per Physical Properties,

 Matters are made up of particles. Particles are very small. They are small beyond of our imagination.

Estimating how small are the particles of matter. With every dilution, though the colour becomes light, it is still visible.

There are following characteristics of particles of matter.

1. Particles of matter have space between them.

For example, Lemonade (nimbu paani) Particles of lemon evenly distributed in water. Particles of one type of matter get into the spaces between particles of the other. This show that there is enough space between particles of matter.

Due to which a diver is able to cut through water in a swimming pool.

2. Particles of matter are continuously moving.

Particles of matters possess kinetic energy. As the temperature rises, particles move faster. The kinetic energy of the particles increases with the increase of temperature.

Due to which smell of hot sizzling food reaches us several metres away, but to get the smell from cold food we have to go close. 

3. Particles of matter attract each other.

Particles of matter have force acting between them. The force keep the particles together. The strength of this force of attraction is different for different matter.

States of Matter

There are three states of a matter which are as follows

1. Solid 
2. Liquid 
3. Gas
