Equilibrium Question 407
Question: pH of human blood is 7.4. Then $ {H^{+}} $ concentration will be [RPMT 2002]
Options:
A) $ 4\times {10^{-8}} $
B) $ 2\times {10^{-8}} $
C) $ 4\times {10^{-4}} $
D) $ 2\times {10^{-4}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ pH=-\log [{H^{+}}] $ ; $ 7.4=-\log [{H^{+}}] $ ; $ [{H^{+}}]=4\times {10^{-8}}M $
