Equilibrium Question 482
Question: Assuming complete ionisation, the $ pH $ of $ 0.1,MHCl $ is 1. The molarity of $ H_2SO_4 $ with the same $ pH $ is [KCET 1998]
Options:
A) 0.2
B) 0.1
C) 2.0
D) 0.05
Show Answer
Answer:
Correct Answer: D
Solution:
$ pH=1 $ means $ [{H^{+}}]={10^{-1}} $ M Hence $ [H_2SO_4]=\frac{{10^{-1}}}{2}=\frac{1}{20}=0.05 $ M
