CuSO4
Obserations:
Oxidation-Reduction reactions:
Zn + CuSO4
(9V-positive terminal)
graphite
(9V- negative terminal)
Observations
Zn + CuSO4 (No current) Zinc turned black in CuSO4, Copper had NC in zinc nitrate
Cu + Zn(NO3)2
(No Current)
Cu + Zn(NO3)2
(9V - negative terminal)
graphite
(9V-positive terminal)
H₂SO4 (9V)
H₂SO4 (ignition of gas)
With no NH3
Pale blue drop
With NH3
Slightly paler blue
Black coating coming off the Zn and moving towards the graphite
Turned Black
Turning orange and breaking up, reaching towards the ZN
Graphite appeared to dissolve into gray liquid which moved
towards the copper
Formed a gas which pushed the H₂SO4 out of the pipette
Made a popping sound and we felt the pipette 'pop'
