Write the balanced molecular and net ionic equations for the reaction between aluminum metal and silver nitrate. identify the ox
asambeis [7]

Well in this case, silver nitrate is reduced:

Ag<span>+  </span><span>+  </span>e<span>−  </span>→ Ag(s) ↓

 

Meanwhile, the aluminum is oxidized forming a positive ion:

Al(s<span>)  →  </span>Al<span>3+  </span><span>+  3</span>e−

 

To get the overall reaction,  we add the half equations so that the electrons are eliminated:

Al(s<span>)  +   3</span>Ag<span>+  </span><span>→  </span>Al<span>3+  </span><span>+  3</span>Ag(s)

 

And similarly:

Al(s<span>)  +  3</span>AgNO3(aq<span>)  →  </span>Al(NO3)3(aq<span>)  +  3</span>Ag(s<span>)</span>
