⚔️🔬 Science 🔬⚔️ The importance of science is well known today. Science is not just limited branch, it is very wide branch and extend study of the basics of science makes a new branch of science. For example, Biology is branch in which the study of living being occurred, Chemistry the study of chemical, Microbiology the study of microorganisms, cell biology the study of all types of cell....etc....etc. But science does not seem to be as important as it should be. Now people understand that there is no alternative without science. Every one know that the science is a great career field, this is also a good education field, that's all there is to it. Still, we can say that ' Science is the one of the army of our country '. What is this nonsense....... How is that........ So let to prove this sentence, with evidence.... At first I would like to say that, we can't imagine the world without Science, because Science has given us so much
⚗️ SOLUTIONS⚗️
In the every day life we make tea, coffee, soups....etc....etc it's nothing but the solutions. In chemistry language The product formation after mixing of two or more than two components is call as the 'solution'.
*Solution÷" Solutions are the mixture of two or more than two components".
Depends on the size of the components,solutions are classifieds into three types ÷
A} Coarse mixture ÷ it is formed when the sizes of the constituent components are relatively bigger ,
E.g. - mixture of salt and sugar.
B} Colloidal dispersion ÷ it is formed when the size of particles dispersed in solvent are are in the rang of 10^-7 to 10^-4 cm . Colloidal solutions are heterogenous ,can easily separated.
E.g.- arsenic sulphide solution.
C} True solution ÷ the true solution is formed when soluble substance are dissolved in solvent. The size of the particles dissolved are very small .
A true solution are homogenous , can't separated into components by simple mechanical method.
#Type of solutions#
*Solid solution ÷ "A solid solution of two or more metals or of a metal or metals with one or more non metal is called Alloy or Solid Solution"
Examples of Alloys :
*Duralumin is an alloy of aluminum and copper, maganesim and manganese.
*Babbitt metal is a soft alloy of tin, antimony , copper and lead.
*Stainless steel is an alloy of iron , chromium , nickel , manganese , nitrogen and carbon.
*Solid solution are necessarily solid alloys*
E.g. sodium amalgam {Na(Hg)}
Zinc amalgam {Zn(Hg)}. Etc...
'Many metals from alloys, all the properties of the pure metals are improved when they form solid solutions ', e.g. alloys
