A) \[12\]
B) \[8\]
C) \[10\]
D) \[6\]
Correct Answer: A
Solution :
Milli mole of \[HCl=40\times 0.10=4\text{ }mole\] Milli mole of \[NaOH=0.45\times 10=4.5\text{ }mole\] Balanced mole \[=4.5-4=0.5\] Total volume \[[O{{H}^{-}}]=\frac{0.5}{500}={{10}^{-2}}\] \[pOH=2\] \[pH=14-pOH=14-2=12\]You need to login to perform this action.
