    I'm thinking about investigating the electrical properties of salt solutions for my practical A2 coursework.
    I've discovered that they act as an electrolyte and if an electrode is applied they can conduct a current.
    But i'm confused, how does the salt solution actually allow current to pass through?

    Because when the salt is dissolved into the water it breaks down into Na+ and Cl- ions and these are what "carry current".

    I think.

    They do. Current is just the flow of any charged particle. In wires its the free electrons, in salt solutions its the ions.
