Question

chapter 9 pre lecture
predict whether each of the following compounds are nonelectrolyte,weak electrolyte, or strong electrolyte.
A) C12H22O11(AQ)+H2O(l)<--- 2C6H12O6(aq)
B) 2O3(AQ)-->3O2(g)         C)CH3NH2(AQ)+H2O(I)---> CH3NH3+(AQ)+OH-(AQ)
D) LiOH(S)--> li+(AQ)+OH-(AQ)
E) HBr(AQ)-->H+(AQ)+Br-(AQ)
D) LiNO3(S)--> Li+(AQ)+NO3-(AQ)
F) HF(AQ)--> H+(AQ)+F-(AQ)
G) Ba(OH)2(s)--> Ba2+(AQ)+2OH-(AQ)

Answer 1

A) C12H22O11(AQ)+H2O(l)<--- 2C6H12O6(aq) = nonelectrolyte

B) 2O3(AQ)-->3O2(g)   = nonelectrolyte      

C)CH3NH2(AQ)+H2O(I)---> CH3NH3+(AQ)+OH-(AQ) = weak electrolyte

D) LiOH(S)--> li+(AQ)+OH-(AQ) = strong electrolyte

E) HBr(AQ)-->H+(AQ)+Br-(AQ) = strong electrolyte

D) LiNO3(S)--> Li+(AQ)+NO3-(AQ) = strong electrolyte

F) HF(AQ)--> H+(AQ)+F-(AQ) = weak electrolyte

G) Ba(OH)2(s)--> Ba2+(AQ)+2OH-(AQ) = strong electrolyte
