What is an electrolyte?

• An ion-containing mixture that conducts electricity

• A metal that conducts electricity

• A plastic that conducts electricity

• A ceramic that conducts electricity

What type of electrolyte do wet cells use?

• Liquid electrolyte

• Solid electrolyte

• Paste electrolyte

• Plastic electrolyte

What type of electrolyte do dry cells have?

• Paste, plastic, or ceramic solid electrolyte

• Liquid electrolyte

• Gas electrolyte

• Metal electrolyte

What is the role of the anode in an electrochemical cell?

• It gains electrons and forms a metal by reacting with a positively charged ion.

• It loses electrons which go into the circuit and produces positively charged ions.

• It remains neutral and does not participate in the reaction.

• It gains electrons and produces negatively charged ions.

What type of Energy Conversion Happens with your toaster?

What is a characteristic of a secondary cell?

• It cannot be recharged.

• It can be recharged by applying a voltage in the reverse direction.

• It is used only once and discarded.

• It produces a constant voltage regardless of usage.
