Explanation:
When a strong acid, say reacts which a weak base, say
, the reaction is shown below as:-
The salt further reacts with water as shown below:-
Formation of lowers the pH value of the solution as more hydrogen ions leads to less pH.

Explanation:
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses donates protons and thus forming conjugate base
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
Suppose acid Ha is getting dissociated in its solution and after dissociation it donates its proton to water molecule and forms conjugate base. Where as water (acting as a base) accepts protons and forms conjugate acid.
HA = Acid
= Base
= Conjugate base
= Conjugate acid
For example:
Sulfuric acid dissociating in its solution to form conjugate base and conjugate acid.
Sulfuric acid = Acid
= Base
= Conjugate base
= Conjugate acid
Explanation:
Sodium has atomic number of 11 and its electronic configuration is given by:
The nearest stable electronic configuration to sodium is of the neon. So, in order to attain stability of noble gas it will loose its single electron.
Sodium has single valency that is 1.
Let nbe the valency of the ion 'X'
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the formulas for all the possible compounds that sodium can form with the other ions will be:
