what is the solution in chemistry |definition of solution

What is the solution in chemistry and definition of the solution? How many types of solutions are presents etc. 

SOLUTIONS 

Chemical: 

Any substance that is present in the lab shelf, in its original container & not involved in any reaction or process.

Reagent: 

Chemical solution of a certain concentration (%age Normal, Molar, etc.) that is present in the lab, being used directly in the reaction or process

Solution: 

A homogeneous mixture that has the same chemical composition and physical properties everywhere is called a solution. The solution has two main parts;

Solvent: 

Larger amount in solution e.g. Water in sugar solution     

Solute: 

Lesser amount in solution e.g. sugar in sugar solution

Solvation/Hydration: 

Interaction between solvent and solute in a solution called solvation. If H₂O is used as a solvent then the solvation process will be termed Hydration.

STRENGTH OF SOLUTIONS:

Parts per million (ppm): 

The number of milligrams in one liter of solution is the number of ppm solution, as 10mg in 1000ml of distilled water will be 10ppm solution

Normality:  

Gram equivalent weight of the substance in 1L of the solution is 1 Normal (1N) solution

Molarity:   

1 molar weight in one-liter solution is 1 Molar (1M) solution.

Molality:  

1 molar weight in one liter of solvent is 1 Molal (1m) solution.

Percent solution: the amount of solute in 100 ml solution.

Types of percent solutions

1. Volume/volume

2. Weight/volume

3. Weight/weight

VARIOUS FORMULAE USED DURING SOLUTION PREPARATION:

1.     N1V1=N2V2

2.     Volume = weight /specific gravity   

3.     Actual volume = volume x 100 / purity
