Le Chatelier’s principle – ലേഷാറ്റ്ലിയര്‍ തത്ത്വം
Le Chatelier’s principle states that when a system at equilibrium is disturbed by a change in temperature, pressure, or concentration of a counteract the change and restore equilibrium.

Chemical equilibrium – കെമിക്കൽ സന്തുലിതാവസ്ഥ
Chemical equilibrium is a state of balance between the forward and reverse reactions in a chemical reaction. At this point, the concentrations of the reactants and products remain constant, and the rate of the reaction is equal in both directions. A reaction at equilibrium can be shifted by an external change in temperature, pressure, or …
Reversible reaction – ഉഭയദിശാ പ്രതി പ്രവര്‍ത്തനങ്ങള്‍
A reversible reaction is one in which the reactants can be converted into products, and the products can be converted back into the reactants. This type of reaction occurs when the reactants and products are at equilibrium with each other. Examples of reversible reactions include the Haber process, the combustion of hydrocarbons, and the reaction …

Preparation of ammonia in the laboratory – ലബോറട്ടറിയിൽ അമോണിയ തയ്യാറാക്കൽ
In the laboratory, ammonia can be prepared by combining an aqueous solution of ammonium chloride and sodium hydroxide. The reaction is as follows: NH4Cl + NaOH → NaCl + H2O + NH3 The resulting ammonia solution can then be collected in a gas-tight container such as a bottle or flask. To prepare the solution, an …

Ammonia (NH3) – അമോണിയ
Ammonia (NH3) is a colourless gas with a strong, pungent odour. It is a compound of nitrogen and hydrogen, and is commonly found in nature and industry. It is used in a variety of applications, including fertilizer production, cleaning products, and food and drug manufacturing.
Concentration of ores – അയിരുകളുടെ സാന്ദ്രണം
Concentration of ores is the process of increasing the percentage of the desirable minerals in the ore by removing the unwanted materials. The process of concentration includes crushing, grinding, sieving, leaching, magnetic separation, froth flotation, and electrostatic separation.
Ore of metal – ലോഹത്തിന്റെ അയിര്
Metal ores are minerals or rocks that contain a valuable metal or metal compounds. Examples of metal ores include copper, gold, and iron ore.
Copper plating on iron bangle – ഇരുമ്പ് വളയിൽ ചെമ്പ് പൂശുന്നു
Copper plating on iron bangle is a process that involves electroplating a thin layer of copper onto the surface of an iron bangle. This is done by submerging the iron bangle in a copper sulphate bath that has been electrically charged. An electrical current is then passed through the copper sulphate solution, causing copper ions …

Electroplating – ഇലക്ട്രോപ്ലേറ്റിംഗ്
Electroplating is a process in which a thin layer of metal is deposited onto the surface of an object. This is usually done for decorative purposes, to improve corrosion resistance, or to improve the electrical conductivity of the object. The process involves passing an electric current through a solution containing ions of the desired metal, …
Practical utility of electrolysis – വൈദ്യുതവിശ്ലേഷണത്തിന്റെ പ്രായോഗിക പ്രയോജനം
Electrolysis has many practical uses, including water purification, electroplating, electroforming, and the production of hydrogen and oxygen gas. It can also be used to separate dissolved ions from a solution, such as in the production of synthetic elements from their salts. Additionally, electrolysis can be used to clean surfaces, to coat objects with a thin …
