Question

Answer 1

Google is your friend (unless you need to use primary sources). For example, after shave:

Answer 2

You can also go and pick up some litmus paper. It's sold to test the pH of pools, so it shouldn't be too hard to find. Then you can test them yourself. Or just google them.

Answer 3

litmus paper, or pH paper should be sold at all chem stores, some grocery stores, and a few specialty stores. you can also make a somewhat good pH solution using red cabbage, though it is hard to get a precise reading.

how much precision do you need? is a range good, or to what decimal place do you need?
