Equilibrium Question 273
Assuming complete ionisation, the pH of $ 0.1,M,HCl, $ is 1. The molarity of $ H_2SO_4 $ with the same pH is 0.05 M [Pb. PMT 2002]
Options:
0.1
0.2
C) 0.05
2.0
Show Answer
Answer:
Correct Answer: A
Solution:
The pH of 0.1M $ HCl=1 $ Ionization of $ H_2SO_4 $ takes place in two steps. $ H_2SO_4 $ ⇌ $ {H^{+}}+HSO_4^{-} $ ; $ HSO_4^{-} $ ⇌ $ {H^{+}}+SO_4^{-,-} $
