Which are strong, weak, or non electrolytes?

potassium iodide
acetone
silver iodide
all molecular when dissolved in water

and

hydroiodic acid
weak conductor when aqueous
covalent compounds
sulfuric acid


Thanks!

Hi, so to understand this we just need to be able to define what strong, weak and non electrolytes contain.
An electrolyte is something that when put into water will conduct a current, and in order to do that, the molecule must be able to break up into ions - dissociate.
Strong - in the interest of this problem: things that dissociate 100% in water
weak - partial dissociation in water
non - basically insoluble


Strong:
KI: is a ionic molecule, this means it will always dissociate 100%
HI: strong acid, 100% dissociation
H2SO4: strong acid, 100% dissociation

Weak:
Weak conductor when aq
Covalent compounds - usually doesn't just break into ions

Non:
All molecular
AgI - this is insoluble
acetone

Hope that helps!

weak conductor when aqueous: is a non electrolyte
Covalent compounds: non electolyte(BKZ they dont have ions)
Sulfuric acid: strong electrolyte
hydroiodic acid: strong electrolyte
