In a galvanic cell, the electrolyte solutions typically consist of aqueous solutions of salts. These salts dissociate into ions in water, allowing for the movement of ions and the flow of electrical current. The electrolyte solutions are often composed of cations (positively charged ions) and anions (negatively charged ions). The specific electrolyte solutions used in a galvanic cell depend on the specific reaction and the electrodes involved. For example, a common galvanic cell, the Daniell cell, uses a copper sulfate solution as the electrolyte for the copper electrode and a zinc sulfate solution for the zinc electrode.
