1 Answer

Answer :

Buffers can resist the charge of its PH value therefore they are required in chemical analysis, pharmaceuticals, electroplating, photography, beverage industry, microbiology molecular biology, soil science and in quantitative analysis.Our blood is best example of buffer solution having PH 7.35. If it decreases upto 7 or goes upto 8 death may occur.
