Problem

If we want to precipitate copper metal from an aqueous solution of CuSO 4, which of the following reactants should we add to our solution?

Choose 1 answer:

a. I2(s)

b. Ag(s)

c. Zn(s)

d. AgNO3(aq)

Solution

We are asked to identify the reactant that would displace Cu from CuSO4 to form copper metal.


In a single displacement reaction, one element displaces (replaces) another element from a compound. The more reactive metals displace the less reactive hydrogen or metals from compounds.
