  1. A is mixed. The first H ionizes at 100% so it is a strong electrolyte. The second one, however, has a k with it (about 0.012) so it is a weak electrolyte.
    CuS is not soluble in water. I don't know how you classify it but since it doesn't dissolve it has no ions and I would go with a non-electrolyte.
    HF is weak.
    Zn(NO3)2 is readily soluble in water to form ions. It is a strong electrolyte.

  3. Actually, I should not have included all of that extra material with the answer. The problem asked about electrolytes and not about ionization. Therefore, I should have answered "strong electrolyte" and stopped at that point. But there is no charge for the extra information. :)
