Can a solution contain only cations?

  1. For example, can Cu2+ be the only ionic species present in an aqeuous solution, without anions such as nitrate. (Hydroxide ions ignored)

    No, solutions are always electrically neutral.

    That is, it is possible for a small drop to have a small charge, but nothing close to bulk solution containing only cations or only anions. Just like any charged object it will discharge at first occasion.
  4. In case you succedeed to make it, I would strongly advise you to stay many metres apart :smile:
