How many moles of are required to oxidize 1 mole of in acidic medium? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Redn: $MnO_4^- + 8H^+ + 5e^- \rightarrow Mn^{2+} + 4H_2O$. <br>Oxidn: $Sn^{2+} \rightarrow Sn^{4+} + 2e^-$. <br>Stoichiometry: 2 moles $KMnO_4$ oxidize 5 moles $Sn^{2+}$. <br>For 1 mole $Sn^{2+}$, $2/5 = 0.4$ moles $KMnO_4$. [6, 29]
