Equilibrium Question 377
Question: When $ {10^{-8}} $ mole of $ HCl $ is dissolved in one litre of water, the $ pH $ of the solution will be [CPMT 1973, 94; DPMT 1982]
Options:
8
7
C) Above 8.0
D) Below 7.0
Show Answer
Answer:
Correct Answer: D
Solution:
As the solution is acidic, $ pH<7 $ . This is because $ [H^{+}] $ from $ H_2O $
$ ({10^{-7}}M) $ cannot be neglected in comparison to $ {10^{-7}} $ .
