Types of cells

Question 1

what is the most common primary cell and what does it include

Answer 1

zinc-carbon cell. zinc casing acts as a negative electrode and a carbon rod which acts as a positive electrode. paste of emmonium chloride acts as the electrolyte.

Question 2

when are zinc-carbon primary cells commonly used

Answer 2

for AA or AAA batteries

Question 3

what happens when a zinc-carbon primary cell discharges

Answer 3

the zinc casing eventually wears away and the corrosive contents of the electrolyte can leak nout

Question 4

button cell

Answer 4

contains mercury being reduced at the anode and zinc being oxidised at the cathode

Question 5

primary cell

Answer 5

a battery designed to be used once and discarded, and not recharged with electricity or reused. the electrochemical reaction occuring in the cell is not reversible. reactants are stored within the cell and will eventually run out

Question 6

secondary cell

Answer 6

has the same structure as a primary cell, with the anode and cathode swapped places. its a type of electrochemical battery that can be charged, discharged into a load and recharged many times.
