Difference Between Acids and Bases

[Tiffany_Cacy_3D]

When you are trying to decide wether a molecule is an acid or a base is there more ways to determine this other than if the molecule donates or accepts electrons? I know there are some other indicators but what are they and are they as accurate as looking at whether they receive or donate electrons?

Some other indicators are pH values (above 7 is alkaline [base] and less than 7 is acid), and that H+ is usually found in relation to acids, while OH- is usually found in relation to bases.

You can also tell by whether it has H+ or OH-. However, it's actually the same thing, since H+ attracts electrons and OH- repels electrons. You can interpret repelling electrons as "giving" electrons out; attracting electrons as receiving electrons.

According to the Bronsted Lowry definition, acids donate protons and bases accept protons.
