# How do you write the balanced molecular and net ionic equations for the reaction between aluminum metal and silver nitrate? What are the oxidation and reduction half-reactions?

Jul 26, 2017

Well, $\text{silver nitrate}$ is reduced..........

#### Explanation:

$A {g}^{+} + {e}^{-} \rightarrow A g \left(s\right) \downarrow$

And aluminum is oxidized......

$A l \left(s\right) \rightarrow A {l}^{3 +} + 3 {e}^{-}$

And we add the half equations such that the electrons are eliminated...

$A l \left(s\right) + 3 A {g}^{+} \rightarrow A {l}^{3 +} + 3 A g \left(s\right)$

And likewise.......

$A l \left(s\right) + 3 A g N {O}_{3} \left(a q\right) \rightarrow A l {\left(N {O}_{3}\right)}_{3} \left(a q\right) + 3 A g \left(s\right)$
