When you add water to draining soap you'll see the ph go down everytime. Then when you add more water you'll see it go down more and more. When you test spit the ph goes down about 1/2 every time you put water into the spit. when you test acids you'll see that it goes down every time you add water it goes down. Every time you put water in soda it goes up about 5 so its a acid.
