Solution and Solubility
This lesson covers the concepts of solution, solute, and solvent. It defines solubility and explains different types of solutions, including saturated, unsaturated, and super saturated solutions. Factors affecting solubility and calculations related to solubility are also discussed.

Water and Its Properties
This lesson covers the composition of water, including its chemical formula H2O. It explains the physical properties of water, such as its states (solid, liquid, gas), boiling and melting points, and its ability to dissolve various substances. The lesson also discusses the importance of water in liv
- 16:30 “A solution is a special type of homogeneous mixture composed of two or more substances. An example that you have in the house is salt. You place your salt in water, you mix it together with the spoon. You will notice tha...”
- 14:42 “When the substance dissolved in a substance, it is called a solute. Now, any substance that is dissolved in a liquid solvent to create a solution is called a solute. Example is a chalk. When a chalk is placed in a water,...”
- 17:19 “Now, the salt solution, you cannot see the salt any longer. And when you try to use the process of filtering, point the salt solution in a filter for them, you will not be able to get the salt back. Colloid. Colloid is a...”
Oxides of Carbon
This lesson covers the two types of carbon oxides: carbon monoxide and carbon dioxide. It explains their formation, characteristics, and methods of preparation in the laboratory. The lesson also defines the term allotrope and discusses the economic importance of these oxides.
- 32:09 “made of whatever in meta, ammonia meta, or radical, all right, so the two, one of the two hydrogen atoms in the molecule, so it's partially replaced, don't forget that, all right, partially replaced, when it is partially...”
- 32:57 “soluble in water, that's a solid word, this part is showing us here, all right, so and so on, and so forth, this is a question of showing that to us, how that happens, so properties of transocarbonyl, of course, action o...”
- 27:17 “preparing them in the laboratory, how we can prepare this in the laboratory. Well, basically, for the soluble transocarbonyl, or soluble ones, or soluble salt, so like the transocarbonyl now, salt, so the water, the solu...”
Definition and Classification of Chemicals
This lesson defines chemicals and explains their various forms, including solids, liquids, and gases. It also classifies chemicals their hazardous nature and discusses safety measures when using them.
- 13:50 “involves a solute material and a solvent and the form what is referred to as solution. Take, for example, what's every one of us, we are used to, that's drinking of Gary. When you pour the Gary into the water, it mixes p...”
- 14:37 “the solute material which is placed on the liquid does not dissolve properly. Then we have colloid, which is the third mixture type. Now, for colloid, the materials which are two or more elements or constituent elements...”
- 13:00 “to the original constituents elements. What are mixtures? Mixtures are materials made up of two or more substances. Now, the difference between these compounds is that they are not chemically combined. Mixtures are physi...”
Chemical Symbols and Formulae
The lesson covers the symbols of the first 20 elements and how to write chemical formulae and equations. It explains the differences between elements, compounds, and mixtures, as well as the concept of radicals and valency. The laws of conservation of mass and constant composition are also discussed
- 07:31 “with a radical, I put brackets. So the formula is C-A-O-H2 for potassium. Hydrozyde. I believe you understand that example. The next is, how do I name? How do I name compounds? How do I name formulas? When they stand tha...”
