Read the following chemical equation: Ti + 2Cl2 → TiCl4 Which statement best identifies and describes the reducing agent in the
goldenfox [79]

Answer: Ti is the reducing agent because it changes from 0 to +4 oxidation state.

Explanation:

  • Firstly, we need to identify the reducing agent and the oxidizing agent.
  • The reducing agent: is the agent that has been oxidized via losing electrons.
  • The oxidizing agent: is the agent that has been reduced via gaining electrons.
  • Here, Ti losses 4 electrons and its oxidation state is changed from 0 to +4 and Cl₂  gains one electron  and its oxidation state is changed from 0 to -1.
  • So, Ti is the reducing agent because its oxidation state changes from  0 to +4.
  • Cl₂ is the oxidizing agent because its oxidation state changes from 0 to -1.
  • Thus, The right answer is Ti is the reducing agent because it changes from 0 to +4 oxidation state.
