Equilibrium Question 446
Question: The $ pH $ value of $ 0.1MNaOH $ solution is (when there is a given reaction $ [{H^{+}}],[O{H^{-}}]={10^{-15}} $ ) [CPMT 1997]
Options:
A) 13
B) 12
C) 11
D) 2
Show Answer
Answer:
Correct Answer: A
Solution:
$ [O{H^{-}}]={10^{-1}}M $ ; $ pOH=1 $
$ pH+pOH=14 $ ; $ pH=14-1=13 $ .
