Hey, maybe I can help

Since ph is a concentration of hydrgen ions , the acidity or alkalinity of water the Ph 7 is neutral, below 7 is acid , above 7 is basic.
As an example lemon juice and vinegar are acids, lava soap and baking soda are bases, since you going to be working with PH. One thing that you need to know is that why do ph changes color and the bases of PH, such the caculations and more and from there , you would be able to get a head start on you project , best of luck to you.

ask brainygirl she in the same grade as you... well different types of acid has their own colour so it may be the acid strength that could affect could it? I'm not really good at these things.
