classify the compounds into electrolytes and nonelectrolytes.

If my test substances were, HCl,HNO3,NH4OH,NaCl,HC2H3O2,Sucrose,HgCl2,ethanol.

electrolytes-->HCl,HNO3,NH4OH,NaCl,HC2H3O2

nonelectrolytes-->Sucrose,HgCl2,ethanol

So if these are correct, Should i write answer of question like this??

Thank you

Well, yes you can write them like this. I think using colon will be slightly better ':'

pure acetic acid is a very weak electrolyte
why do you think HgCl2 is a nonelectrolyte?

sarah1004 · Nov 2, 2009, 08:47 AM

I took experiment today.

I was confusing that HgCl2 is non or weak elec.

Do you think HgCl2 is weak elec.??

Thanks

HgCl2 is an ionic compound, consisting of Hg^2+ and Cl^-, it's the mercury salt, mercury chloride. It will therefore dissociate upon electrolysis, hence it is an electrolyte.

okay , thanks.
so nonelectrolytes is only two, that sucrose and ethanol.

yeah i took experiment today in that morning
I did that i put some conductivity thingy in the solution and i saw very little light on HgCl2
So i was confusing to decide that its elec or non.

So THanks^^
