Acid-Base reaction / reaction of metallic and Non-Metallic Oxides with acids and bases

By Sachin Joshi

 

I) Acids and Bases reacts with each other.


- > When Acids reacts with Bases to form Salt and water as product. This reaction is also called as neutralisation reaction.

Acid + Base ---------> Salt + Water 

Example:-

i) NaOH (aq) + HCl (aq) ---------> NaCl (aq) + H2O(l)

ii) MgOH (aq) + HCl (aq) -------> Mg(OH)2 (aq) + H2O (l)

iii) LiOH (aq) + HCl (aq) ---------> LiCl (aq) + H2O (l)

iv) Ca(OH)2 (aq) + H2SO4 (aq) ---------> CaSO4 (aq) + H2O (l)

II) Metallic Oxides reacts with Acids:-

- > When Metallic Oxides reacts with Acids it gives Salt and Water as products.
Metallic Oxide + Acid ------> Salt + Water
Example :-
 i)  CuO (s) + HCl (aq) -------> CuCl2 (aq) + H2O (aq)
black colour                    blue-green colour

->We notice that tht the colour of the solution becomes blue-green due to the formation of copper(II) chloride in the reaction .

ii) CuO (s) + H2SO4 (aq) -------> CuSO4 (aq) + H2O (aq)

• Nature of Metallic Oxides :-

- > The nature of Metallic Oxides are Basic in nature hence Metallic Oxides reacts with Acids to give Salt and Water.

III) Reaction of Non-Metallic Oxide with Base :-

-> When Non-Metallic Oxide react with Base to give Salt and water.

Non-Metallic Oxide + Base ------> Salt + Water

Example :-
i) CO2 (g) + 2NaOH (aq) -------> Na2CO3 (aq) + H2O (l)
ii) CO2 (g) + Ca(OH)2 (aq)-------> CaCO3 (aq) + H2O (l) 

• Nature of Non-Metallic Oxide :-
- > The nature of Non Metallic Oxide is Acidic in nature hence Non-Metallic Oxides reacts with Bases to form Salt and Water.


• IMPORTANT QUESTIONS :-

a) Show with the reaction how acid and base react with each other.
b) What is neutralisation reaction ?
c) Show with the reaction between Metallic Oxide react with Acid using suitable example.
d) What is the nature of Metallic Oxides ?
e) Why Metallic Oxides do not react with acids.
f) Sow with the reaction between Non- Metallic Oxide react with Base using suitable example.
g) What is the nature of Non-Metallic Oxides ?
h) Why Non- Metallic Oxides do not react with Bases.

What is Photosynthesis ?

By Sachin Joshi
                        WHAT IS PHOTOSYNTHESIS? Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose and other organic compounds. It is a complex biochemical process that occurs in the chloroplasts of plant cells and involves the absorption of light by pigments such as chlorophyll. The overall equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2 In this equation, carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) through a series of reactions that involve the transfer of electrons and the formation of ATP, a molecule that stores energy. Photosynthesis occurs in two main stages: the light-dependent reactions and the light-independent reactions. In the light-dependent reactions, light energy is absorbed by chlorophyll and other pigments, and used to generate ATP and NADPH, which are ener...

Chemical reaction and equation

By Sachin Joshi
                   CHAPTER NUMBER I ---------------------------------------------------------------------------- CHEMICAL REACTION AND EQUATION  * Chemical reaction : -               A chemical reaction is a process in which one or more substances are converted into one or more different substances. During a chemical reaction, the bonds between atoms in the reactants are broken and new bonds are formed to create the products.  Chemical reactions can be represented by chemical equations, which show the reactants on the left-hand side of the equation and the products on the right-hand side. For example, the chemical equation for the reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O) is:  2H2 + O2 → 2H2O  This equation shows that two molecules of hydrogen gas and one molecule of oxygen gas react to form two molecules of water.  * Chemical reactions can ...

Acids-Bases And Salts/Importance of pH in Everyday Life

By Sachin Joshi
  • Importance of pH in everyday life :- --------------------------------------- I) Are plants and animals pH sensitive ?   -> Our body works within the pH range of 7.0 to 7.8 .  -> Organisms survive in this narrow pH range change.  -> When pH of rain water is less than 5.6 then it is called acid rain . It lowers the pH of river water when mix with it and the survival of aquatic life becomes difficult. II) pH of Soil :- pH of Soil   -> plants required a specific pH for their healthy growth.  -> In most plants, the optimum pH range is from 5.5 to 7.0 , but some plants will grow in more acid soil or may require a more alkaline level.   III) pH in our digestive system :- pH of digestive system   -> Our stomach produces hydrochloric acid which helps in the digestion of food without harming the stomach.   -> During indigestion stomach produces too much acid which causes pain and irritation . To get ride from thi...
