Look for the compound which in a dilute solution has the most ions. for instance, in b

KNO3 is completed ionized,2 ions per molecule
Ca(NO3)2, three ions, but one of them carries two charges, so in fact one moleucle can break up to carry 5 net charges.
HNO3, 100 precent dissoacated, but two ions per molecule.
Answer: circle calcium nitrate.

Yes, UCI students. We haven't learned this in lecture.

I know that HCl is one of the correct choices

hey UCI!

a. HCl
b. HNO3
c. NaOh
d. K2CO3, also in the lab we did. it all depends on the cation (k, li, and na) which one has the highest mass
e. AlCl3 (that was in the lab we did.)

Do we really need to know all of this for the lecture AND lab??

Are these going to be on the test?
