Vocabulary: Acids/Bases & Ocean Acidification

Arrhenius Acid

it’s the first model to explain the behavior of acids and bases (Arrhenius acids dissociate and form hydrogen cations, H⁺ ions, in aqueous solution)

Arrhenius Base

ionic compound that releases a hydroxide ion, OH^-

Hydrogen Ion (H⁺)

produced by acids (In solution, it does not exist by itself)

Hydronium Ion

H₃O⁺ forms when the dissociated H⁺ ion combines with a water molecule

Carbon Dioxide

CO₂

Water

H₂O

Carbonic Acid

H₂CO₃ made from H⁺¹ and CO₃^2-

Bicarbonate / Hydrogen Carbonate

HCO₃^-1 made from H⁺¹ and CO₃^2-

Calcium Carbonate

CaCO₃ made from Ca²⁺ and CO₃^2-

Brinsted-Lowery Acid

Hydrogen-ion H⁺ donor

Bronsted-Lowry Base:

hydrogen-ion H⁺ acceptor

Conjugate acid

is the ion or molecule formed when a base gains a hydrogen ion
