Problem

A group of students are asked to identify which of the following solutions represents a strong
.
solution A has 3 acid molecules: 1 is dissociated into separate H+ and A- particles and 2 stayed together as HA molecules. solution B has 6 acid molecules: 2 are dissociated and 4 stayed together as HA molecules. solution C has 5 acid molecules. All 5 of them are dissociated into separate H+ and A- particles.
Two student explanations are shown below:
Student 1: Solution B represents a strong acid because it contains the most acid.
Student 2: Solution C represents a strong acid because all of the acid is completely dissociated.
Which student(s) identified the strong acid with the correct justification?
