A) 7
B) 9.2
C) 4.74
D) 14
Correct Answer: C
Solution :
\[pH=p{{K}_{a}}+\text{log}\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}\] equimolar means \[\frac{\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }}{\text{ }\!\![\!\!\text{ Acid }\!\!]\!\!\text{ }}=1\]; \[\]\[pH=4.74+0=4.74\]You need to login to perform this action.
