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}} $ .
