Question

whst is a buffer solution

Answer 1

Buffer solution is the solution of weak base with strong electrolyte of weak acif with strong electrolyte . It Resist the change of pH

For example

Acidic buffer ..
CH3COOH → CH3COO- + H+ 

CH3COONa → CH3COO- + Na+ 

pH = p^ka + log[salt]/[Acid]

in this case .. common ion effect also take place 

Another example ...

Basic buffer

NH4Cl → NH4+ + Cl-

NaCl → Na+ + Cl- 

pH = p^ka + log[Salt]/[Base]

Answer 2

Buffer solution:

Buffer solution:buffer solution is defined as a solution which resists drastic changes in pH when a small amount of strong acid or strong base or water is added to it.
