Litmus paper only tells you if it is acidic or not, not how acidic it is. There are other kinds of indicator papers though, which are used just like litmus paper, dip and read, but which can change to several different colors, depending on the pH of a solution. If you know someone who works in a hospital laboratory or other chemical lab, perhaps they could get some for you. For soda, you are dealing with very mild acidity, so you would need an indicator paper designed for that pH range. There are many different kinds. An indicator paper which turns different colors for pH 1, pH 2, pH 3 and so on would not be useful to you, because soda will never have those pH values. Ideally you need an indicator paper that shows different color changes for pH values between 5 and 7, in graduations of 0.2. (5.0, 5.2, 5.4, 5.6, etc.) Good luck.<br><b>References : </b><br>biologist A pH meter is certainly the best, but it is an expensive piece of equipment not available to everyone.

Essentially how it works is there is a part that you put into the solution you are trying to test. That part is connected via cable to a part that must remain dry, but gives you a digital readout (i.e numerical data) and is accurate to about a hundredth of a pH unit. See if you can borrow one from someone, or ask if you can use it under supervision. Many chemistry courses at the end of high school involve using a pH meter, so your school may have one.<br><b>References : </b><br> There is a device called a pH meter.
