Please help me with homework?
Please help with chemistry task (corrosion)
*In the steel plate inserted copper rivets.
1. How corrosion will start in this construction if atmosphere is wet?
2. Specify which metal is anode and which – cathode?
3. Write the corresponding electron-reaction equations.
Lancenigo di Villorba (TV), Italy
YOU ASKED :"In the steel plate inserted copper rivets."
QUESTION n.1
"How corrosion will start in this construction if atmosphere is wet?"
Wet atmosphere forms very thin layer of water onto metallic surface, e.g. onto plate and onto rivets.
Once atmosphere formed water film onto Steel Plate, THIS LATTER LOOSES IRON(II) IONs INSIDE WATER FILM WHILST COPPER RIVETS IS CONVERTING OXYGEN GAS INTO HYDROXIDE IONs.
QUESTION n.2
"Specify which metal is anode and which – cathode?"
Since I specified already that STEEL PLATE IS LOOSING IRON(II) IONs, IT IS TAKING OXIDATION OF ITSELF : it will result an electrodical anode.
I already specified that COPPER RIVETs ARE CONVERTING OXYGEN IN HYDROXIDE IONs : rivets play like electrodical cathode.
QUESTION n.3
"Write the corresponding electron-reaction equations."
THE ELECTRODICAL HALF-REACTIONs FOLLOW
Steel Plate (Anode) : Fe(aq) ---> Fe++(aq) + 2e
Copper Rivets (Cathode) : O2(aq) + 2 H2O(aq) + 4e ---> 4 OH-(aq)
I hope this helps you.
