How do I calculate how well a liquid conducts electricity?

  1. Sep 26, 2009 #1
    Which one of the following substances would
    likely be the best conductor of electricity in
    the pure liquid state (that is, when melted)?
    1. bromine (Br2)
    2. barium fluoride (BaF2)
    3. water (H2O)
    4. phosphorus trichloride (PCl3)
    5. methane (CH4)



    I don't know any relevant equations, I really would prefer to be taught how to solve this, than just get the answer
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Do you know how the current can be conducted? What must be present?
