What are Acids and Bases?

Acids, by definition, are proton donors, so will donate a H+ ion to a base. Examples of acids may be HCl or ethanoic/acetic acid (a.k.a. vinegar).

Bases, by contrast, are proton acceptors, so will accept the acidic proton from the acid, if the reaction allows it to. Examples of bases are NaOH or NH3 (Ammonia).
