The pH of four solutions W, X, Y, Z are 4, 6, 8, 10 respectively, therefore
none of these solutions is acidic
the pH of Y is made more acidic by addition of distilled water
Z is the most acidic solution
W is the most acidic solution
X is neutral
Correct answer is D
W is the most acidic solution since 4 < 6 < 8 < 10. The lower the value on the pH scale, the more acidic a solution.
