Introduction :

In today's article I will tell you about the definition,explanation and properties of Acids,bases and alkalis. After studing this article you will know Acids,bases and alkalis and easily difference between Acids,bases and alkalis so don't skip and see completely.

Acids,bases and alkalis

1.Acid 

Naming : 

The word acid is derived from Latin word "acidus" which means sour.

Properties :

* Acid have sour test.

* It turns blue litmus paper red.

* It change the colour of an acid-base indicators.

* Aqueous solution of acid conduct electric current.

* Strong acid are very corosive to skin and fabrics.

Properties :

* Bases have bitter test.

* These are soapy in touch.

* It turns red litmus paper blue.

* It change the colour of an acid-base indicator.

* Their Aqueous solution contact electricity. 

* Strong base are corosive.

3.Alkalis :

Definition :

Alkalis are those base which are water soluble.

Properties :

* In Aqueous solution it produces hydroxide ion(OH).

* All alkalis are bases.

* But all bases are not alkalis. 

Conclusion :

As we know the above article is on Acids,bases and alkalis. So we concluded from this article summary of Acids,bases and alkalis. Acid: Sour test substance are acid. Base : Salt & water produced when react with acid.Alkalis : Water soluble bases.
