A) 10
B) 0.1
C) 1
D) 2
Correct Answer: B
Solution :
\[pH=p{{K}_{a}}+\text{log}\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}\] \[5.8=4.8+\log \frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}\] or \[\text{log}\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}=1.0\] \[\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}=\text{antilog}\,\,1.0=10\] \ \[\frac{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}=\frac{1}{10}=0.1\]You need to login to perform this action.
