Question

Which 1.0 M aqueous solution would produce the most ions?

 

 

A. HF

 

B. Li2CO3

 

C. Al(NO3)3

 

D. KOH

 

 

 

Answer 1

1.0 M HF - HF is a weak electrolyte and will not ionize completely

1.0 M Li₂CO₃ is a strong electrolyte and ionizes completely to yield 2.0 M Li⁺ and 1.0 M CO₃^2-

1.0 M Al(NO₃)₃ is a strong electrolyte and ionizes completely to yield 1.0 M Al³⁺ and 3.0 M NO₃^-

1.0 M KOH is a strong electrolyte and ionizes completely to yield 1.0 M K⁺ and 1.0 M OH^-

 

So, obviously the most ions are produced by Al(NO₃)₃ because it yields 4 ions.
