Answer to Question #184604 in General Chemistry for Aich80

Question

"Standard Redox Reactions"

Using the standard reduction potentials, determine whether the following reactions are spontaneous under standard conditions:

A. Magnesium reducing chlorine to chloride ions

B. Silver reducing hydrogen ions to hydrogen

C. Cl₂ (g) + 2 i^-1(aq) = 2Cl^-1 (aq) + i₂ (s)

Answer 1

Using standard reduction potential ;

• Magnesium reducing chlorine to chloride ions is a spontaneous reaction
• Silver reducing hydrogen ions to hydrogen is a spontaneous reaction
• Cl₂ (g) + 2 i^-1(aq) = 2Cl^-1 (aq) + i₂ (s) is a non spontaneous
