An electrolyte is neutral, so what allows it to conduct exclusively positive ions in a battery and not electrons?
I see, I want to understand what physical process allows either conductor (the Cu or the electrolyte) to transport a exclusively a positive or negative chargeYou're objecting to one "neutral" medium transporting charge carriers, and you have no objection to a second "neutral" medium transporting charge carriers. It's the same question. What physical processes are you interested in understanding?
In an electrolyte, a the charges in a substance such as NaCl are divorced from one another and form ions i.e. negative and positive charges. If there are equal proportion of each in an electrolyte(making the substance neutral), what then makes the electrolytes cater to positive ions in particular?Cu atoms are playing "hot potato" with electrons given a potential difference between the ends of the conductor that is sufficient that electrons can make the jump, or be tossed from one atom to the next. What are analogous structures/entities in an electrolyte solution?
