A) 2
B) 3
C) 4
D) 1
Correct Answer: C
Solution :
Given, that \[C=0.1\text{ }M\] \[\alpha =0.1%=0.001\] \[\therefore \] \[[{{H}^{+}}]=C.\alpha =0.1\times 0.001\] \[=1.0\times {{10}^{-4}}\] \[\therefore \] \[pH=-\log [{{H}^{+}}]\] \[=-\log {{10}^{-4}}\] \[=4\]You need to login to perform this action.
