Which of the following are strong electrolytes? (Several choices may be correct.)

[ ] CH3OH (methyl alcohol)

[X] KCl

[ ] C3H5(OH)3 (glycerin)

[ ] H2SO4

[ ] NH3

[X] NaOH

[ ] C12H22O11 (sucrose, or table sugar)

[ ] HC2H3O2 (acetic acid)

I got this whole problem wrong on wileyplus. That's all i can think of. Weak electrolytes are acids and strong electrolytes are ones that dissociate when placed into water. Did I miss something  ???

Both statements are incorrect. I suggest you look up wikipedia, on 2 articles.
first, http://en.wikipedia.org/wiki/Electrolyte and second, http://en.wikipedia.org/wiki/Strong_electrolyte

If you believe you have understood them, add these to your list:
mark if strong/weak/non electrolyte (assume all to be in their aqueous solutions)
--->K2SO4.Al2(SO4)3.24H2O
---> Li[AlH4]
---> Sulphur
---> HCOOH
---> CO2
---> Mercury
---> Oil
