All proton acceptors are base by the B&L theory description.
Examples: all hydroxides OH- , ammonia NH3 , most metal- and some other oxides O2-

Acid compounds will donate hydrogen ions and base compounds will accept hydrogen ions.
A base is the measure of the amount of hydroxide ions, according to the arrhenius theory.
An acid and a base are very different compounds.
Brønsted-Lowry acid-base theory
see link below for answer
The Bronsted-Lowry theory is that acids and bases are defined by the way they react with each other. Liquid ammonia and acetic acid are examples.
Acid compounds will donate hydrogen ions and base compounds will accept hydrogen ions.
Halochromic compounds: compounds with different colors dependings on the pH.
Salts are ionic compounds that are formed by neutrlization of an acid & a base.
Carbon
A base is the measure of the amount of hydroxide ions, according to the arrhenius theory.
