Copper sulfate and zinc battery
Components of copper sulfate and zinc battery
sulfate and zinc battery is an example of electrochemical cell.
It consists of a copper plate and a zinc plate which play the role of
electrodes and which also correspond to two terminals.
These two electrodes are immersed in an ionic solution of copper
sulphate: it is said that this solution is an electrolyte.
connecting a multimeter in voltmeter mode at the terminals of the
battery, we can measure a voltage of about 1 V.
This voltage is only positive when com terminal on the multimeter is
connected to the zinc and the V terminal is connected to copper.
According to the rules for connecting a multimeter, it can be deduced
- Zinc is the negative terminal.
- Copper is the positive terminal.
