Equilibrium Question 367
Question: Hydrogen ion concentration in mol/L in a solution of $ pH=5.4 $ will be [AIEEE 2005]
Options:
A) $ 3.98\times 10^{8} $
B) $ 3.88\times 10^{6} $
C) $ 3.68\times {10^{-6}} $
D) $ 3.98\times {10^{-6}} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ pH=-\log ,[{H^{+}}] $
$ 5.4=-\log ,[{H^{+}}] $ ; $ [{H^{+}}]=3.98\times {10^{-6}} $ .
