Question

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.

Which letter denotes the area of the graph where both acid and salt are present?

A. A

B. B

C. C

​

Answer 1

Answer:

I think the answer is *c*

Explanation:

as it is slightly above 7ph so generally it will contain some salts and acids

Answer 2

The correct option will be option c.

In area A and B the pH of the solution is very high and it shows that the solution is strongly basic.

In area D the pH of solution is very low and it shows that the solution is strongly acidic.

Whereas in the area C the pH is slightly more than 7 which indicates that the solution is neither too acidic not too basic .

So we conclude that the area of the graph where both acid and salt are present is C.
