Voltaic Cell Concepts and Applications

Mrs. T introduces an assignment on voltaic cells, explaining their function as batteries through redox reactions that convert chemical energy to electrical energy. She describes the components of voltaic cells, including the anode, cathode, and salt bridge, and explains the flow of electrons and ions. Students are instructed to examine diagrams and submit their observations on Google Classroom. Mrs. T offers extra help sessions and encourages students to reach out with questions.

What is the main task students need to complete for the assignment?

• Create a video about voltaic cells.

• Note similarities between provided pictures of voltaic cells.

• Draw a diagram of a voltaic cell.

• Write an essay on voltaic cells.

What type of reaction is used in a voltaic cell to generate electricity?

• Synthesis reaction

• Combustion reaction

• Redox reaction

• Decomposition reaction

What is the purpose of the voltmeter in a voltaic cell?

• To act as a salt bridge

• To measure the voltage

• To store ions

• To facilitate electron flow

In a voltaic cell, what is the role of the anode?

• It is where ions are stored.

• It is where oxidation occurs.

• It is where reduction occurs.

• It is where electricity is measured.

What is the function of the salt bridge in a voltaic cell?

• To maintain electrical neutrality by allowing ion flow

• To allow electrons to flow

• To store chemical energy

• To measure voltage

Which direction do electrons flow in a voltaic cell?

• From salt bridge to wire

• From anode to cathode

• From electrolyte to electrode

• From cathode to anode

Why are electrolyte solutions necessary in voltaic cells?

• To provide a medium for electron flow
