Equilibrium Question 276
Question: The $ pH $ of 0.1 M solution of a weak monoprotic acid 1% ionized is [UPSEAT 2001; Pb. PMT 2001]
Options:
A) 1
B) 2
C) 3
D) 4
Show Answer
Answer:
Correct Answer: C
Solution:
$ C=0.1M;\alpha =1%;({H^{+}})=C\times \alpha $
$ =0.1\times \frac{1}{100}={10^{-3}} $ ; $ ({H^{+}})={10^{-3}} $ ; pH = 3.
