CHEMICAL REACTION

In our day today life we are using lot of things, and it may contains some chemicals. Let see what are the major chemical substances that we using.

Silve Anklet :-

The lustrous white colour of the silver anklet slowly changes its colour into black colour due to formation of silver sulphide

2Ag + H2S + O2 (in air) ----> Ag2S + H20


2nd chemical reactions

Lead Nitrate and Potassium iodide solution (both are colourless )

When Lead Nitrate Solution is slowly added to the Potassium iodide solution it forms a Yellow colour precipitate. It is called Lead Iodide (PbI2)


3rd Chemical Reactions

Calcium Oxide (Cao) reacts with water (H2O) to  --->  Ca(OH)2 (Calcium Hydroxide ) which is slaked lime.


4th reaction

Calcium Hydroxide ( Ca(OH)2 ) reacts slowly with carbon dioxide (CO2) in air to form a thin layer of calcium carbonate (CaCO3) (marble)


5th reaction


Coal (Carbon C ) + Oxygen (O2) ---> CO2  ( Carbondioxide ) in Combustion process.
