Final answer:
HCl(aq) is both an Arrhenius acid and a Brønsted-Lowry acid, as it dissolves in water to yield hydronium ions and donates a proton to NaOH. NaOH acts as both an Arrhenius base and a Brønsted-Lowry base because it accepts a proton from HCl and gives off hydroxide ions when dissolved in water.
Step-by-step explanation:
The compound HCl(aq) in the reaction HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq) can be identified as both an Arrhenius acid and a Brønsted-Lowry acid. It qualifies as an Arrhenius acid because it dissolves in water to yield hydronium ions (H3O+), and as a Brønsted-Lowry acid because it donates a proton to the NaOH, which is a Brønsted-Lowry base.
An Arrhenius base is a compound that dissolves in water to produce hydroxide ions (OH−), and a Brønsted-Lowry base is a compound that accepts a proton. In this case, NaOH acts as both an Arrhenius base and a Brønsted-Lowry base because it can accept a proton from HCl and produces hydroxide ions in water.
