Why is this equation used?
pH=7+0.5(pKa–pKb)? This equation is for salt of weak base and weak acid.
Here it is strong base and weak acid. So we should use pH=7–0.5pKb–log C. Isn't it? Please explain
not able to understand what you want to ask.
i would suggest please go through some standard books as rc mukheerjee/ p bahadur. for proper grasp of concept
