OBSERVATIONS
Purple right-side solution and
metal warn; left side metal
has deposits.
Right metal warns away;
left side has deposits.
Right side metals warns
away; left side has
deposits.
Left side warns away;
right side has deposits.
Left side metal warns
away: right-side has
deposits.
Left side warns away:
right-side has deposits.
Analysis
MICROSCOPIC
OBSERVATIONS
Left side electrons flow downward, attracting
additional Ag atoms to join the surface, while right
side electrons travel upward, ionizing and
dispersing the metal atoms into the solution.
zinc releases two electrons and passes into the solution as Zn+2,
making the electrode negatively charged. Ag+ extracted one
electron and deposited it in the electrode, making it positively
charged.
Mg releases two electrons and passes into the
solution as Mg2+, making the electrode
negatively charged. Ag+ lons extract one
electron from the electrode and deposited on the
electrode, making it positively charged.
The left-side electrons travel upwards ionizing
and dispering the Mg atoms. Right-side electrons
flow downwards attracting additional Cu atoms.
The left-side electrons travel upwards lonizing and dispering
the Mg atoms into the solution while the right-side electrons
flow downward attracting additional In atoms to join the
surface.
Mg ionizes and drifts into the solution, electrons
travel upward, right-side electrons travel
downward, attracting new Ag atoms.
