Depends if the solvent is water or not. In H2O, proton donors (H+) are acids; proton acceptors (e.g. OH-) bases; in NH3, the "alkali" ion is NH2-. Look up Lewis acid, Bronsted-Lowry acid, e.g. http://www.meta-synthesis.com/webbook/12_lab/lab.html.
You might also try an experimental definition: if a metal dissolves in the substance, releasing hydrogen, it may be an acid. But then, Al dissolves in NaOH solution (look up amphoteric).

How technical an answer do you want?

Acids are ionic compounds ( a compound with a positive or negative charge) that break apart in water to form a hydrogen ion (H+). Examples: vinegar, lemons, stomach acid, all have acid in them.

Bases are ionic compounds that break apart to form a negatively charged hydroxide ion (OH-) in water. Examples: lye, ammonia.

An acid has a pH < 7 (have a greater concentration of H3O+ ions) while a base has a pH > 7 (lower concentration of H3O+ ions).

A very simple expanation is that acid start with "H" and bases end with "OH". This is not always true, but is a good starting point.

They have completely different sets of properties and react in different ways.

acids are H+ and bases are OH-. acid just has more hydrogen atoms.

are you kidding?

acids release hydrogen when mixed with water they are tart and corrsive

bases are slippery (soap and fat are both basic) and they neutralize acids
