Questions & Step-by-Step Solutions

Which of the following is an example of a non-stoichiometric solid? (2023)
  • Step 1: Understand what a non-stoichiometric solid is. It is a solid that does not have a fixed ratio of its elements.
  • Step 2: Look at the example given, FeO (iron oxide).
  • Step 3: Recognize that in FeO, the ratio of iron (Fe) to oxygen (O) can change. This means it can have different amounts of iron and oxygen.
  • Step 4: Conclude that since FeO can vary in its composition, it is a non-stoichiometric solid.
