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 …

Electrolysis of molten sodium chloride – ഉരുകിയ സോഡിയം ക്ലോറൈഡിന്റെ വൈദ്യുതവിശ്ലേഷണം
The electrolysis of molten sodium chloride involves passing an electric current through the molten salt. As a result, chlorine is released at the anode and sodium is released at the cathode. The overall reaction is as follows: 2NaCl → 2Na + Cl2
Electrolytic cells – വൈദ്യുതവിശ്ലേഷണ സെല്ലുകള്‍
Electrolytic cells are electrochemical cells that use electricity to drive a non-spontaneous reaction. This electricity is typically provided by an external source, such as a battery or power supply. Inside the cell, the electrical current causes ions to move between two electrodes, resulting in a chemical reaction that produces a product. This product can be …
Galvanic cell – ഗാല്‍വാനിക് സെല്‍
A galvanic cell, also known as a voltaic cell, is an electrochemical cell that produces electricity from a chemical reaction. The reaction involves the transfer of electrons from a metal electrode to an electrolyte, which is usually an aqueous solution of an acid or a base. The electricity produced is used to power electrical devices, …
Reactivity series and displacement reactions – ക്രിയാശീല ശ്രേണിയും ആദേശ രാസപ്രവര്‍ത്തനങ്ങളും
Reactivity series: The reactivity series is a list of metals, organized from most reactive to least reactive. The most reactive metals are at the top of the list and include potassium, sodium, calcium, magnesium, aluminium, zinc, iron, and lead. Displacement reactions: A displacement reaction is a type of chemical reaction where one element is displaced …
Reaction of metals with acids – ആസിഡുകളുമായുള്ള ലോഹങ്ങളുടെ പ്രതിപ്രവർത്തനം
Metals generally react with acids to produce hydrogen gas and a salt. The general equation for this reaction is: Metal + Acid → Salt + Hydrogen For example, when zinc reacts with hydrochloric acid, the reaction produces zinc chloride and hydrogen gas: Zn + 2HCl → ZnCl2 + H2
Reaction of metals with air – വായുവുമായുള്ള ലോഹങ്ങളുടെ പ്രതിപ്രവർത്തനം
Metals usually react with oxygen in the air to form metal oxides. This process is known as oxidation. Depending on the type of metal and oxygen, the reaction can be either exothermic (releasing heat) or endothermic (absorbing heat). For example, when iron is exposed to air, it forms iron oxide (rust). Other metals such as …
