Explanation : Vinegar is a good conductor of electricity because an aqueous
solution of acetic acid dissociates in to ions. When sugar is dissolved in water, the solution does not conduct
electricity because of no ions in formed the solution. Salt water is a good conductor of electricity because it is an electrolyte solution and dissociates in to ions in aguenes solution. Distilled water docs not conduct electricity because it does
not contain any impurities.
Explanation : Repulsion and not attraction is a sure test of magnetism. The other magnetic substances which are also non-magnets would only be attracted to a magnet.
