Acid/base rules
Could someone list rules for determining if a compound is an acid or base? It's hard for me to determine it on a case-by-case basis so I was wondering if there are any generalities for acids and bases.

Re: Acid/base rules
I think the general rule of thumb is that acids are proton donors and bases are acceptors. We know that acids give off H+ and bases OH-

Building on the last reply, you can look at the hydrogens in each compound before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions)

Re: Acid/base rules
Just to also add on, I believe that small, positively charged elements, such as Al+3, create a more acidic solution and are known as Lewis acids because they pull electron density towards them, and make the OH bond easier to break.
