Question

What is the purpose of phosphate buffer solution in ecl?

Answer 1

Buffer action is the property of buffer solution to resist any change in its pH value even when very small ammount of base or acid are added to this.

Buffer solution is the aqueous solution containg a mixture of a weak acid and its conjugated base...or weak base with its conjugated acid

Answer 2

Answer:

Phosphate buffered saline (PBS) is a buffer solution commonly used in biological research. The buffer helps to maintain a constant pH. Generally a pH of 7.4 is maintained. The osmolarity and ion concentrations of the solution usually match those of the human body.
