Characteristics bof solution
Answers
Answer: IN Simple Terms,
A solution is a homogeneous mixture of two or more than two substances whose particle size is 0.1nm -1nm. Homogeneous means that the components of the mixture form a single phase.
You must have seen many types of solutions in general such as soda water, sharbat, salt solution etc. You would have seen brass utensils as well which are also homogeneous solution of solid into solid. We can prepare solutions of solid-liquid, solid-solid, solid-gas, liquid-solid, liquid-liquid, gas-solid, gas-liquid and gas-gas. Gasoline, alloys, air, starch solution etc. are examples of solutions.
Explanation:
Examples of Solutions
Sugar-water, salt solution, brass, alloys, alcohol in water, aerosol, air, aerated drinks such as Coca-Cola etc. are the examples of solutions. When we work with chemistry, we generally prepare many types of solutions such as copper in water, iodine in alcohol etc.
Types of solutions
Solutions can be divided into following types of the basis of quantity of solute in a solution –
Unsaturated Solution – The solution in which still we can add more solute at a given temperature is called unsaturated solution.
Saturated Solution – The solution in which we cannot dissolve more solute in the solvent at a given temperature is called saturated solution.
Supersaturated Solution – The saturated solution in which we add more solute by raising the temperature or pressure is called a supersaturated solution. In these solutions generally crystals start forming.
Properties of a Solution
A solution possesses following properties –
A solution is a homogeneous mixture.
The constituent particles of a solution are smaller than 10-9 metre in diameter.
Constituent particles of a solution cannot be seen by naked eyes.
Solutions do not scatter a beam of light passing through it. So, path of the light beam is not visible in solutions.
