A) ​1 only
B) 2 only
C) 3 only
D) ​1, 2, and 3​
E) 2 and 3

Quizplus · Accepted Answer

1) is true because strong electrolytes, by definition, completely dissociate into ions in solution.
2) is also true because spectator ions do not participate in the reaction, but are still present before and after the reaction.
3) is true because the net ionic equation only includes the species that participate in the reaction (i.e. those that are consumed or produced).
