Question

A water solution whose pH is 4_______. a. is always neutral b. is always acidic c. is always basic d. might be neutral, basic or acidic.

Answer 1

C. Is Always Basic

When pH < 7 the solution is acidic
When pH = 7 the solution is neutral
When pH > 7 the solution is basic

Answer 2

A water solution whose pH is 4 is always acidic. Acidic pH is always less than 7, that of greater than 7 is basic. The solution with pH of 7 is called a neutral solution. pH is a measure of H+ concentration hence the acidic solutions have more H+ concentration
