Equilibrium Question 292
Question: One litre of water contains $ {10^{-7}}mole $ hydrogen ions. The degree of ionization in water will be [CPMT 1985, 88, 93]
Options:
A) $ 1.8\times {10^{-7}}% $
B) $ 0.8\times {10^{-9}}% $
C) $ 3.6\times {10^{-7}}% $
D) $ 3.6\times {10^{-9}}% $
Show Answer
Answer:
Correct Answer: A
Solution:
1 litre of water contains 1000/18 mole. So degree of ionization $ =\frac{{10^{-7}}\times 18}{1000}=1.8\times {10^{-7}} $ %.
