To Choose: The correct option.
Explanation of Solution
Introduction:
In the given titration graph, the x -axis denotes the number of drops of base added to the acidic solution and the y -axis represents the pH of the solution. The smallest division along the x -axis is 25 drops and that along the y-axis is pH=2.
A solution is said to be neutralized when the concentration of acid and base is equal in it.
For a neutral solution, pH is equal to 7.
From the graph, the drop count corresponding to pH=7 is 50.
Conclusion:
Hence,Option C, 50 is the drop count at which the acid and base are exactly neutralized.
