Answer:
= +ve, reaction is spontaneous
= -ve, reaction is non spontaneous
= 0, reaction is in equilibrium
Case 1: when copper metal is combined with aqueous zinc sulfate.
Here copper is undergoing oxidation ad thus acts as anode and zinc is undergoing reduction , thus acts as cathode.
= standard electrode potential =
Where both are standard reduction potentials.
Thus as is negative , the reaction is non spontaneous.
Case 2: when zinc metal and aqueous copper sulfate solution are combined.
Here zinc is undergoing oxidation ad thus acts as anode and copper is undergoing reduction , thus acts as cathode.
= standard electrode potential =
Where both are standard reduction potentials.
Thus as is positive , the reaction is spontaneous.
Answer:
Single displacement reaction.
Explanation:
Hello!!
In this case, since the reaction between silver nitrate and copper metal is:
As silver was forming silver nitrate, due to the presence of copper, which has the capacity to displace silver out of the salt, we notice the formation of solid silver and a resulting copper (II) nitrate which is blue in aqueous solution.
Therefore, this is a single displacement reaction, because the the lonely copper displaced the silver.
Best regards!
