Using the following portion of the activity series for oxidation half reactions Li(s)→ Li⁺(aq)+ e^- Al(s)→ Al³⁺(aq)+ 3e^- Fe(s)→ Fe²⁺(aq)+ 2e^- Pt(s)→ Pt²⁺(aq)+ 2e^- Determine which pairs of reactions will occur. A)Al(s)with Fe²⁺(aq)and Pt(s)with Li⁺(aq) B)Fe(s)with Al(s)and Al³⁺(aq)with Pt²⁺(aq) C)Fe(s)with Pt²⁺(aq)and Al(s)with Pt²⁺(aq) D)Li(s)with Al³⁺(aq)and Fe(s)with Al³⁺(aq)

Question

Quizplus · Accepted Answer

The activity series indicates that a more reactive metal can displace a less reactive metal from its compound. Fe(s) can reduce Pt²⁺(aq) because Fe is more reactive than Pt. Similarly, Al(s) can reduce Pt²⁺(aq) because Al is more reactive than Pt.
