WHAT IS SOLUTION?, And Different types of Solutions

Image
A binary solution is nothing but a homogeneous mixture of two substances. These two substances or components are the solute and the solvent.  The solute is the substance that gets dissolved. It is present in a smaller quantity. On the other hand, the solvent is the substance that dissolves the solute. It is present in a comparatively larger quantity. There are different types of solutions. But, what is the basis of their differentiation?   Types of Solutions Solutions are of different types, based on a number of criteria, like the difference in the solute or the solvent etc. Let us now look at the different types of solutions, based on different criteria. On the basis of water as Solvent  Based on the whether the solvent is water or not, solutions are of two types. Aqueous solutions:  These solutions have water as the solvent .  Examples of such solutions are sugar in water, and carbon dioxide in water, etc. Non-...

What is Atom ? Definition :-   Atom is the smallest indivisible particle of the matter. Atom is made of        electron, proton and neutrons. P ARTICLE ELE CTRON P ROTON NEUTRON Discovery Sir. J. J. Thomson (1869) Gold stein (1886) Chadwick (1932) Nature of charge Negative Positive Neutral Amount of charge 1.6 x 10 -19 Coloumb 1.6 x 10 -19 Coloumb 0 M ass 9.11 x 10 -31 kg 1.672614 x 10 -27 kg 1.67492 x10 -27 kg    Electrons were discovered using cathode ray discharge tube experiment.Nucleus was discovered by Rutherford in 1911. Cathode ray discharge tube experiment:-   A cathode ray discharge tube made of glass is taken with two electrodes. At very low pressure and high voltage,current starts flowing through a stream of particles moving in the tube from cathode to anode. These rays were called cathode rays. When a perforated anode was taken, the cathode rays struck ...

What Is Humalin ????

Image
  What Is Humalin ? Humulin  is the man-made insulin, which is made by the recombinant DNA by genetic engineering. Humulin  R (insulin (human recombinant)) is a hormone that is produced in the body used to treat diabetes.   A small piece of circular DNA called a plasmid is extracted from the bacteria cell or yeast. Humulin N is injected under the skin. It should not be injected into muscle or veins. Doses of insulin are measured in units. U-100 insulins, including Humulin N, contain 100 units/mL. With the Humulin N U-100 vial, it is important to use a syringe that is marked for U-100 insulin preparations.
