Help, confused at identifying

Postby Daniel Kim 1D » Sun Jul 28, 2019 9:07 pm

I was wondering if there was a list of acids or like a way to tell if one is a base.

Ways to help identify if it is an acid or base include charge, because that will promote if the electron pair will be accepted or donated. Another way to tell is of the acid has a Hydrogen that it could donate, and for bases they would typically have a hydroxide OH-.

There are some common substances like H20, NH3, HCO3-, HSO4- which can donate or accept, making them amphoteric.

Regarding testing, if you are comfortable and familiar on working through the acid base homework problems, that should suffice for identifying acids and bases.

Bases often have an electron pair that is available for bonding which allows it to accept Hydrogen ions. Whereas the acid is able to dissociate because of differences in electronegativity between a hydrogen atom and other atoms in the molecule. If you look at a chemical equation you can figure out which is which by looking at the reactants vs the products and seeing which lost a hydrogen ion and which gained one.
