Question

give a difference between an alkali and base

2.what is meant by neutralisation reaction.

3.what are strong bases ?give example

4.what is meant by weak acid?

Answer 1

Hi friend.........

Ans 1. An alkali is a soluble base and hence a subset of base, While bases are not necessarily soluble in water and furnishes Hydroxyl ions.

Ans 2. When acids and bases reacts with each other and form salts and Water, the reaction is referred to as neutralisation reaction.

Ans 3. The bases which go under complete ionisation are referred to as strong bases.

Eg:- AlO3, KOH, etc.

Ans 4. The acids which go under partial ionisation during a reaction, they are referred to as weak acids.

HOPE IT WILL HELP U. . . . . . .

Answer 2

heya!!! friend!!

here's ur answers:-

1.the difference between alkali and base are ,bases which are completely soluble in water are called alkalies. whereas base is a substance which furnishes hydroxyl ions.

2.neutralisation reaction is the reaction in which acids react with base to form salt and water .

3.strong bases are those which dissociate into positive ion and OH-(minus) completely in aqueous solution for example ,NaOH,KOH are strong bases.

4.weak acid - an acid which doesnot dissociate into ions completly in an aqueous solution and there exists an equilibrium between ions and unionised molecules is called weak acid.
