Basic Concepts of Chemistry

This experiment demonstrates Avogadro's Law by comparing different gases such as helium, nitrogen, and methane. Under the same temperature and pressur...

This experiment demonstrates the difference between a mixture and a compound using iron filings and sulphur powder. One sample is heated to form a bla...

This experiment explains concentration in a solution. By adding different amounts of solute to a fixed amount of solvent, it shows that more solute ma...

This experiment explains that density depends on how closely molecules are packed. When molecules are tightly packed, the object becomes denser. When ...

This experiment demonstrates how different materials respond to an applied force. When rubber is struck, it compresses and returns to its shape, showi...

In this experiment, we are going to perform the flame test to identify specific metal ions (cations) present in a given salt. We do this by mixing a s...

This experiment demonstrates the Law of Conservation of Mass by showing that the total mass of a system remains unchanged before and after mixing, as ...

This experiment demonstrates the Law of Definite Proportions by showing that potassium chlorate decomposes into products in a fixed mass ratio, confir...

In this experiment, we observe the temperature changes during two chemical reactions to identify whether they are exothermic or endothermic. Sodium hy...

This experiment demonstrates the process of dissolution by showing that salt or sugar particles mix uniformly with water, forming a solution as the pa...

This experiment demonstrates the separation of a mixture containing ammonium chloride, sand, and common salt by using three different physical separat...

In this experiment, students use pH paper to determine the approximate pH of different solutions, including acids, bases, soil extract, and fruit juic...

In this experiment, ammonium chloride is heated to observe its decomposition into ammonia and hydrogen chloride gases. The gases are identified using ...
