Solution and Suspension

Hi people! Welcome back!:D I hope you had a better understandings of classification of matter through the previous lesson. Okay, today's lesson. we would be learning about what is a solution and suspension. Now, tighten your seat belts and lets rock and roll!

Firstly, before you learn what is a solution and suspension, you know these things first: What is a solute?
What is the solvent?

Basically, a solute is:

• a substance that dissolves.

And, a solvent is:

• a substance that a solute dissolves in.( forms the main part of the solution.)
  

Thus, a solution is:

• a mixture formed when 1 or more solute dissolves in a solvent.
• can be of any physical state.
• water as solvent is called aqueous solution
• when a solution is formed, the solute breaks down into tiny particles such as atoms and molecules that mix completely and evenly with the particles of the solvent.
  

And, a suspension is:

• when a solid solute does not dissolve in the solvent and are sufficiently large to settle to the bottom over time

Solution and suspension's appearance:
Solution Suspension
-Homogeneous mixture -heterogeneous mixture
-clear solution, uniform throughout -cloudy and uneven

What is a saturated solution?
-one which contains the maximum amount solute dissolved in a certain amount of solvent at a particular temperature.

What is solubility?
-the maximum mass of a solute which can dissolve in 100g of a solvent a particular temperature.

Factors that affect solubility

1. Nature of solute
2. Nature of solvent
   
3. Temperature of solvent

What is rate of dissolving?
-time taken for the dissolve process, from the time the solute is added to the solvent, until it has completely dissolved

Factors that affect the rate of dissolving

1. Surface area of the solute ( the smaller the particle size, larger the surface)
2. Temperature of the solution (higher the temperature)
3. Rate of stirring (faster the rate of stirring)

That's all for today's lesson. Thank you for support. I hope this lesson will once again benefit in your studies. Remember to tune again next week for a new lesson! Enjoy! :D Feel free to ask me and doubts.
