A) \[0.1\,\,m\]
B) \[0.2\,\,m\]
C) \[1.0\,\,m\]
D) \[10.0\,\,m\]
Correct Answer: C
Solution :
\[pH=p{{K}_{a}}+\text{log}\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}\]; \[5.5=4.5+\text{log}\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ 0}\text{.1 }\!\!]\!\!\text{ }}\] \[\text{log}\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{0.1}=5.5-4.5=1\] \[\frac{\text{ }\!\![\!\!\text{ Salt}]}{0.1}=\]antilog 1 = 10 ; \[\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }=1\]You need to login to perform this action.
