Answer:

Option A, The pH of the solution is 2.7 and the solution is acidic

Explanation:

As we know,

pH = - log [H3O+]

Substituting the given values, we get

pH = - log [2.1 x 10-3 M]

pH = - (-2.678)

pH = 2.678 or 2.7

The solution is acidic as pH value is less than 7

Hence, option A is correct
