Equilibrium Question 474
Question: In a solution of acid $ {H^{+}} $ concentration is $ {10^{-10}}M. $ The pH of this solution will be
Options:
A) 8
B) 6
C) Between 6 and 7
D) Between 3 and 6
Show Answer
Answer:
Correct Answer: C
Solution:
As the solution is acidic, pH < 7. This is because $ [{H^{+}}] $ from $ H_2O $
$ ({10^{-7}}M) $ cannot be neglected in comparison to $ {10^{-10}} $ M HCl.
