Acetylsalicylic acid; bases, acids, and the pH scale.

How acidic is acetylsalicylic acid (aspirin) on the pH scale? I am interested in this subject because I’ve never studied chemistry, and I thought it would be fun. I wanted to learn about acids, bases and neutralization. I also thought this would be fun because I’ve always wanted to do a chemistry project. To answer the question, you may need to know what some things are. Before the first question is asked, there are some key terms and vocabulary you have to know first.
pH is a number used by scientists to show the concentration of hydrogen atoms in a solution. The pH scale generally goes from 0 to 14. The letters pH stands for potential hydrogen. If a solution is at 77 degrees Fahrenheit (or 25 degrees Celsius) and has a pH level below 7 it means that the solution is acidic. A pH level above 7 means the solution is basic. A pH level of 7 means the solution is not acidic, nor basic; and it is neutral. One example of a neutral solution is water.
