Question 14

Acids, Bases and Salts

The pH of four solutions W,X,Y,Z are 4, 6, 8, 10, respectively, therefore

  1. A.none of these solutions is acidic
  2. B.the pH of Y is made more acidic by addition of distilled water
  3. C.Z is the most acidic solution
  4. D.W is the most acidic solution
  5. E.X is neutral
Show the answer and explanation

Answer: D (W is the most acidic solution)

Explanation

The lower the pH, the more acidic the solution. W has the lowest pH (4), so it is the most acidic.
