B. Na2CO3 dissociates into more particles in solution
C. NaCl is more soluble than than Na2CO3
D. NaCl does not contain a polyatomic ion.

Na2CO3 simply has more ions per molecules (you have a total of 5 ions) versus sodium chloride only has 2.

So which one seems like the right answer?

jfraser · Answer

@alias $Na_2CO_3$ dissociates into $three$ ions, not $five$, but you are generally correct

anonymous · Answer

oops, brain fart... but my reason still holds. more ions = better conductivity

sorry if I confuse anybody
