How does nh4cl and naoh form a buffer??

Dear Student 

​​​​​NH₄Cl and ​​​​​NH₄OH makes a buffer solution as buffer solution are of two types:
(1) a weak acid together with a salt of the same acid with a strong base.  These are called acid buffers e.g CH₃COOH + CH₃COONa.
 (2) a weak base and its salt with a strong acid. These are called basic buffers. e.g NH₄OH +NH₄Cl.

​​​​​NH₄Cl and ​​​​​NaOH does not makes a buffer solution
