Question

What is the correct representation of reaction occurring when HCl is heated with $MnO_{2}?$

• A. $MnO_{4}^{-} + 5Cl^{-} + 8H^{+} \rightarrow Mn^{2 +} + 5Cl^{-} + 5H_{2}O$
• B. $MnO_{2} + 2Cl^{-} + 4H^{+} \rightarrow Mn^{2 +} + Cl_{2} + 2H_{2}O$
• C. $2MnO_{2} + 4Cl^{-} + 8H^{+} \rightarrow 2Mn^{2 +} + 2Cl_{2} + 4H_{2}O$
• D. $MnO_{2} + 4HCl \rightarrow MnCl_{4} + Cl_{2} + H_{2}O$

Answer 1

Answer: (B)

$MnO_{2} + 2Cl^{-} + 4H^{+} \rightarrow Mn^{2 +} + Cl_{2} + 2H_{2}O$

Answer 2

: $MnO_{2} + 4HCl \rightarrow MnCl_{2} + |Cl_{2} + 2H_{2}O$
