article for my video in youtube

My english, heterogenous and homogenois
All matter ca be classify as pure substance and mixture.
Mixture also devided as homogenous and heterogenous mixture.
a homogenous mixture is one that contains only one type of  a compound or element.
a heterogenous mixture is made of different substances that remind physically separated.
solutions are homogenous mixture of two or more substances, a solution is made of two components, namely the solute and the solvent.
a solute is substance dissolved in another substance, known as a solvent. A solvent is present in a larger quantity than the solute.
there are three type of solutions that is solid, liquid and gasses.
a true solutions is always homogenous in nature. The particles of a solution cannot be seen by the neaked eyes as the particles are less than 1 nanometter.
the particles of solution do not scatter a beam of light. Hence, the path of light is not visible in a solution.
the solute particles in a solution cannot be separated from the solution by physical means.
the particles do not sattle down. If a solution is kept undisturbed for a while.
the concentration of a solution, is the known quantity of a solute in a known quality of a solvent. The concentration of a solution can be expressed in two ways.

presentage concentration
(Volume based method)
v/V x 100
Here, v mililiter of solute is dissolved, in V milliliterof solution.
(Weight based method)
w/W x 100
in weight based method, the weight of the known solute dissolved in known weight of solvent is expressed.
a solution that cannot dissolve any more solute at a certain temperature is called as a saturated solution.
a solution that can dissolve more solute at a certain temperature is called as a unsaturated solution.
suspensions are heterogenous mixture in which the particles of two solute do not dissolve but remain floating everywhere in the medium.
colloidsre heterogenous mixture where fine particles are dispersed within a continuous medium, which prevent them from settling down or being filtered.
Milk, foam, cheese, etc. Is the example of colloids.
a colloidal system is made of the dispersed phase and the dispersion medium. In a colloidal system, the very fine particles (dispersed phase) are dispersed in another substance (dispersion medium).
Here, have one video about this leasson, lets wathing and enjoyed.

  1. Explain more depth about dispersion and dispersion media?

    1. Dispersion occurs whenever there is a process that changes the direction of light in a manner that depends on wavelength. Dispersion can occur for any type of wave and always involves wavelength-dependent processes.

  2. How are structural differences in homogeneous solutions and heterogeneous solutions? Please explain to me

  3. Create another example besides the one you mentioned?
