Solutions

 Solution is a homogeneous mixture of two or more components.


If we have a solution of only two components, the solution is called binary solution.

If we have a solution of three components, the solution is called ternary solution.

And if we have a solution of four component that is called quaternary solution.

In this unit, we will discuss about binary Solutions only. In this type of solution, we have a solute and a solvent.

Solute: This component is present in small quantity.

Solvent: This component is present in large quantity.
Solvent determines the physical state is which solution exists


Example: sugar is dissolved in water
Sugar is solute and water is solvent.

Types of solution:

 



Expressing concentration of solutions:

Composition of a solution can be described by expressing its concentration. The latter can be expressed either qualitatively or quantitatively. 
Qualitatively, we can say that the solution is dilute or it is concentrated. 
Quantitatively, we can define concentration in several ways.

Let's talk about success!

  Today's topic is success. Since I am a science teacher, I will explain success the same way I would explain any topic. There are some sections in any topic. Such as the definition of that topic, what are the types in that topic, what is the measurement criteria of that topic and what is the unit and formula of that term? First of all we will understand what is the definition of success? The meaning of success can be different for everyone. For example, earning a lot of money can be success for someone, it can be success for someone to reach a respected post. Strengthening your relationship can be a success for someone. But when you see the essence of all these, that is, you feel satisfaction after getting all the things. So in short we can say that success is achieving something to reach to the satisfaction So in my view there are 4 types of success . 1) Short term success : Short term success is the type of success that we get quickly.By early achievement, I mean t...

Chemical classification of matter.

Image
   The chemical classification of matter is based upon its composition. Different substances differ from each other in their constituents composition. On the basis of chemical, composition matter can be classified as: 1) Pure substance 2) Mixtures. 1) Pure substance : Pure substance is consist of single type of particles. All constituent particles of a pure substance are same in their chemical nature. Example: copper, gold, iron, water, glucose, Sodium chloride etc . Pure substances can be further classified into elements and compounds. A) Elements : The simplest form of a pure substance, which can either be decomposed into nor built from simpler substances by ordinary physical or chemical methods. Example: Sodium, carbon, potassium, Sulphur, helium etc . Elements can further be classified into the following types. i)Metals ii) Non-metals and iii) Metalloids, B) Compounds : A pure substance containing two or more than two elements combined together in a defin...
