A) \[HCl\] is completely ionised at this concentration
B) The ionization of water is negligible
C) The ionization of water cannot be assumed to be negligible in comparison with this low concentration of \[HCl\]
D) The pH cannot be calculated at such a low concentration of \[HCl\]
Correct Answer: C
Solution :
As the solution is acidic, \[pH<7\]. This is because \[[{{H}^{+}}]\] from \[{{H}_{2}}O\]cannot be neglected in comparison to \[{{10}^{-8}}\].You need to login to perform this action.
