Identify the Arrhenius acids: I. HCl II. NaOH III. HNO₃ IV. Ca(OH)₂

Question

Quizplus · Accepted Answer

Arrhenius acids are substances that increase the concentration of hydrogen ions (H+) in aqueous solution. HCl is a classic example, dissociating to produce H+ ions in water. HNO₃ seems to be a typographical error, but if it's intended to represent a compound that releases H+ ions, it would also be considered an Arrhenius acid. NaOH and Ca(OH)2 are bases, not acids, as they increase the concentration of hydroxide ions (OH-) in solution.
