When you hear the word solution, you tend to think of a liquid. However, a solution can be a homogeneous mixture of any phase. These two questions are about a solid solution that has properties of a metal. When some atoms of the solvent are replaced by solute atoms of a similar size, the solution is called a heterogeneous alloy. an intermetallic compound. a substitutional alloy. an interstitial alloy.

Both questions are answered below:

  1. Substitutional alloys
  2. Interstitial alloys

Explanation:

Some atoms of the solvent can be replaced by atoms of relatively similar sizes, allowing for atom exchange or substitution, Whenever these atoms can be substituted within the matrix, it forms a substitutional alloy. Examples include bronze and brass.

Alternatively, some atoms are much smaller in size and cannot successfully be exchanged  for the other. Instead, they get trapped within the matrix. these are called interstitial alloys, e.g steel.
