steel wool with metallic chlorides
« on: August 08, 2006, 02:54:21 AM »
A sample of steel wool is placed in four different beakers(A,B,C,D)
A has CuCl2
B Has PbCll2
C has FeCll2
D has NaCl

What will happend
a) No reactions will take place
b) Reaction in A
c) Reaction in A and C
d) Reaction in D

i thought it was b) Reaction in A since Iron is more reactive than Copper
but the answer says that it is a)
are the answers incorrect?
Thanks ;D
