Arrhenius acids
are substances which produces hydrogen ions in solution, Arrhenius bases are
substances which produces hydroxide ions in solution. A Bronsted-Lowry acid is
a proton donor (usually hydrogen ion). And a Bronsted-Lowry base is a proton
acceptor (usually hydrogen ion). Consider a chemical reaction between HCl and
NaOH. We have the reaction HCl + NaOH à
NaCl + H2O. The hydroxide ions in the NaOH are bases because they accept
hydrogen ions from acids to form water. And an acid produces hydrogen ions in
solution by giving a proton to the water molecule. Therefore, the answer is d.
a Bronsted-Lowry base.
