Say after I did the experiment for titration and I got several results, what are the next steps I should do to check out their concentration? If I don't know what the solutions are and their molecular formua, is it possible to still continue doing the calculations for titration.

Do you know of any steps to calculate concentration involving titration results.

Also, what are possible sources of error?

The [H+] = 3.16 x 10^-4 M and the [OH -] = 3.16 x 10^-11 so the [H+] is bigger than the [OH-] that is as far as I got however, I don't know how to explain if it is a strong acid or not.

The answer to this question is more than likely no because I'm guessing our insides are more sensitive than our skin, but nonetheless I am curious and seek an answer. Thanks in advance.

An atom and a solar system are similar, thus a galaxy is like a molecule, can earth be just an electron in some greater collection of matter beyond our understanding?
