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


Question

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

Options

A) none of these solutions is acidic

B) the pH of Y is made more acidic by addition of distilled water

C) Z is the most acidic solution

D) W is the most acidic solution

E) X is neutral


The correct answer is D.

Explanation:

W is the most acidic solution since it has a pH of 4. Acidic solutions have ph level lower than 7 while neutral is 7 and basic is more than 7. W and X are acidic but W is more acidic because its value is lower than the value for X.
Note: The lower the value, the higher the acidity and the lower the basicity while the greater the value the higher the basicity and the lower the acidity.
