Discussion Overview

The discussion centers around the relationship between soluble salts and their conductivity, exploring whether the solubility of a salt guarantees strong conductivity. Participants consider various examples and scenarios, including the conductivity of salts in solution versus their solid state.

Discussion Character

  • Debate/contested, Experimental/applied

Main Points Raised

  • One participant questions whether soluble salts necessarily imply strong conductivity and asks for reasoning and counterexamples.
  • Another participant mentions that while strong acids or bases imply strong conductivity, soluble salts may not guarantee strong conductivity, suggesting that solubility indicates some level of conductivity but not necessarily a strong one.
  • A participant provides an example of testing Cu(C2H3O2)2, noting it is a soluble salt but recorded weak conductivity, expressing uncertainty about their judgment.
  • One participant proposes that, all other factors being equal, a more soluble salt will lead to a more conductive electrolytic solution due to the presence of more ions.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether soluble salts guarantee strong conductivity, with multiple competing views and examples presented without resolution.

Contextual Notes

Participants express uncertainty regarding the definitions of conductivity in relation to salts and their solutions, and there are unresolved questions about the conditions under which conductivity is measured.

Does a soluble salt necessarily implies a strong conductivity?

Hi johndoe,

You must give us your reasoning first, then we may be able to comment on it. What do you think? Can you think of any counterexamples?

Also, do you mean conductivity of the salt alone, or a solution of the salt in a solvent?

I am working on my lab report, and there is an explanation in the example saying that 'AgNO3 is a strong conductor because AgNO3 is a soluble salt.'

Well I know that strong acid or base implies strong conductivity, but if a salt is soluble I think it only implies that the salt is a conductor but not necessarily a strong one.


salts I mean by ionic compounds alone

Example?
I tested Cu(C2H3O2)2 in my lab with a light blub, it is a soluble salt and I wrote down weak, but I might be wrong with personal judements.

It seems reasonable to say that, all other factors being equal, a more soluble salt will produce a more conductive electrolytic solution because more ions will be present.
