검증된 단계별 안내

Step 1: Understand the concept of a reducing agent. A reducing agent is a substance that donates electrons to another species in a redox reaction, causing the other species to be reduced while the reducing agent itself is oxidized.

Step 2: Look up the standard reduction potentials for the half-reactions of Ti²⁺ and Ni²⁺. The standard reduction potential indicates the tendency of a species to gain electrons and be reduced.

Step 3: Compare the standard reduction potentials. The species with the more negative standard reduction potential is a stronger reducing agent because it is more likely to donate electrons.

Step 4: Analyze the reduction potentials: If Ti²⁺ has a more negative reduction potential than Ni²⁺, it means Ti²⁺ is more willing to lose electrons, making it a stronger reducing agent.

Step 5: Conclude based on the comparison: Determine which ion, Ti²⁺ or Ni²⁺, has the more negative standard reduction potential and thus is the stronger reducing agent.

Reducing Agents

A reducing agent is a substance that donates electrons in a chemical reaction, thereby reducing another substance. The strength of a reducing agent is determined by its ability to lose electrons easily. Stronger reducing agents have a greater tendency to undergo oxidation, which is the loss of electrons.

Standard Reduction Potentials

Standard reduction potentials (E°) are measured values that indicate the tendency of a species to gain electrons and be reduced. A more negative E° value suggests a stronger reducing agent, as it indicates a greater likelihood of losing electrons. Comparing the E° values of Ti2+ and Ni2+ will help determine which is the stronger reducing agent.

Electrochemical Series

The electrochemical series is a list of standard reduction potentials for various half-reactions, arranged from strongest to weakest reducing agents. By examining this series, one can predict the relative strength of reducing agents. The position of Ti2+ and Ni2+ in this series will provide insight into their reducing abilities.

Which is the stronger reducing agent, Ti2+ or Ni2+? Explain.
