Solution
The correct option is ACl− s a Bronsted-Lowry base An Arrenhius acid releases H+ ions while an Arrenhius base is a substance that releases OH− ions in an aqueous solution. HNO3 releases H+ ions and hence, it acts as an Arrenhius acid. A Bronsted-Lowry acid is a H+ ion donor while a Bronsted-Lowry base is a H+ ion acceptor. NH3 acts a Bronsted Lowry base as it accepts a hydrogen ion to form NH+4.
