A student has a solution with a pH of 7. The student adds HF, hydrogen floride, to the solution, hoping to increases the pH of the solution. What is wrong with this student’s approach? You cannot change the pH of a solution. HF is an acid, so it will lower the pH of the solution. The pH of the solution is already as high as possible. The pH is 7, so the solution is already as acidic as possible
