# What is the reducing agent in the reaction 2Na(s) + Cu(NO_3)_2(aq) -> Cu(s) +2NaNO_3(aq)?

$\text{The reducing agent}$ is the species oxidized........$\text{the electron source.}$

#### Explanation:

And sodium is clearly the species oxidized here,

i.e. $N a \rightarrow N {a}^{+} + {e}^{-}$

I don't think this could be accomplished in aqueous solution. The sodium would reduce the water first to hydrogen gas.
