Equilibrium - Result Question 96
####100. The $pH$ value of blood does not appreciably change by a small addition of an acid or a base, because the blood
[1995]
(a) is a body fluid
(b) can be easily coagulated
(c) contains iron as a part of the molecule
(d) contains serum protein which acts as buffer
Show Answer
Solution:
- (d) The buffer system present in serum is $H_2 CO_3+NaHCO_3$ and as we known that a buffer solution resist the change in $pH$ therefore $pH$ value of blood does not change by a small addition of an acid or a base.
