Homework question example:
Pure (deionized water) - strong, weak, non?
Acetone - strong, weak, non?
Solid sugar - strong, weak, non?
I know water is neutral because I memorized that fact, but I have no idea about the concept.
Thank you for the opportunity to help you with your question!
Pure (deionized water) - , non
Acetone - non
Solid sugar - , non
Strong Electrolytes conduct current very efficiently
Completely ionized or dissociate when dissolved in water (single arrow)
a. Soluble Ionic compounds
b. Strong acids (HNO3(aq), H2SO4(aq), HCl(aq))
HNO3--> H+ + NO3- (100% ionization)
c. Strong bases (KOH and NaOH)
KOH -->K + +OH - (100% dissociation)
***covalent substances ionize....ionic substances dissociate
Weak electrolytes conduct only a small current
Slightly ionized in solution (double arrow)
a. Weak acids (organic acids-->acetic, citric, butyric,malic, etc.)
HC2H3O2<==> H+ + C2H3O2-
b. Weak bases (ammonia)
NH3 + H2O<==> NH4+ + OH-
Nonelectrolytes conduct no current
No ions present in solution
a. alcohols, sugars
