The graph given below depicts a neutralization reaction (acid + alkali → salt + water).
The pH of a solution changes as we add excess of acid to an alkali.
A. A
B. B
C. C
D. D
D. D
Explanation:
The pH of the solution becomes less then 7 while both Acid and Salt are presant, So In this above graph, the pH is less then 7 in only point D.
