Question

1.For the first ten reactions, write a balanced reaction for each tube in which a reaction occurred. If there was no reaction, write NR

Answer 1

The equations of reaction occurring in the tubes are as follows:

• 2 MnO₄⁻ + 6 Br⁻ + 8 H⁺ → 2 MnO₂ + 3 Br₂ + 4 H₂O
• 2 MnO₄⁻ + 6 I⁻ + 8 H⁺ → 2 MnO₂ + 3 I₂ + 4 H₂O
• No reaction
• 2 Fe³⁺ + 2 I⁻ → 2 Fe²⁺ + I₂

What are the reactions occurring in the tubes?

The reactions occurring in the tubes are redox reactions.

Based on the table the equations of reaction are as follows:

• 2 MnO₄⁻ + 6 Br⁻ + 8 H⁺ → 2 MnO₂ + 3 Br₂ + 4 H₂O
• 2 MnO₄⁻ + 6 I⁻ + 8 H⁺ → 2 MnO₂ + 3 I₂ + 4 H₂O
• No reaction
• 2 Fe³⁺ + 2 I⁻ → 2 Fe²⁺ + I₂

In conclusion, redox reaction are reactions in which electrons are transferred.
