complete the following sentence: the cathode in a voltaic cell is the electrode

to which anions from the salt bridge migrate
in which oxidation takes place
to which cations from the salt bridge migrate
in which electrons become available

to which cations from the salt bridge migrate

Explanation:

A voltaic cell is an electrochemical cell that uses spontaneous redox reactions to generate electricity. It's composed of a cathode, an anode, and a salt bridge.

In cathode, the substance is gaining electrons, so it's reducing, in the anode, the substance is losing electrons, so it's oxidating. The flow of electrons is from the anode to the cathode.

The salt bridge is a bond between the cathode and the anode. When the redox reaction takes place, the substances produce its ions, so the solution is no more neutral. The salt bridge allows the solutions to become neutral and the redox reaction continues.

So, the cathode produces anions, which goes to the anode, and the anode produces cations, which goes to the cathode. Then, the cathode n a voltaic cell is the electrode to which cations from salt bridge migrate and where the reduction takes place.

Over time the metal will cool and the water will heat up. Eventually the two objects will have the same temperature
