Equilibrium Question 511
Question: If the pH of a solution of an alkali metal hydroxide is 13.6, the concentration of hydroxide is [JIPMER 2000]
Options:
A) Between 0.1 M and 1 M
B) More than 1 M
C) Less than 0.001 M
D) Between 0.01 M and 1 M
Show Answer
Answer:
Correct Answer: A
Solution:
$ pH=13.6 $
$ pOH=14-13.6=0.4 $
$ [O{H^{-}}]=Antilog(-0.4)=0.3979 $ . So the value of $ [O{H^{-}}]between0.1Mand1M $
