If a student were to build a voltaic cell using solid zinc and hydrochloric acid, which of the following equipment would also be needed?
To build a voltaic cell using solid zinc and hydrochloric acid, the student would need the following equipment:
1. Zinc electrode: A piece of solid zinc metal is needed as the anode in the cell.
2. Hydrochloric acid solution: A solution of hydrochloric acid is required to act as the electrolyte in the cell.
3. Glass container: A container, such as a beaker or a glass jar, is needed to hold the hydrochloric acid solution.
4. Copper electrode: A copper electrode is required as the cathode in the cell.
5. Salt bridge: A salt bridge or a porous barrier is needed to connect the two half-cells and allow the flow of ions.
6. Multimeter or voltmeter: A multimeter or voltmeter is required to measure the potential difference or voltage produced by the cell.
7. Wires and clips: Wires and clips are needed to connect the zinc and copper electrodes to the multimeter and form a complete circuit.
8. Safety equipment: Safety goggles and gloves might be necessary while working with hydrochloric acid to ensure safe handling and protect oneself from potential hazards.
It is important to note that when working with chemicals, proper safety precautions and procedures should be followed, and it is recommended to have supervision and guidance from a teacher or professional.
