Coagulation is a ___ reaction.

Explanation:
The idea being tested is whether coagulation involves a chemical change. Coagulation typically forms a solid from a dispersed system, which usually requires chemical transformations—such as ions reacting to form a precipitate or particles linking through chemical bonds to create a new solid phase. This goes beyond a simple physical rearrangement; the end product has a different chemical environment or composition than the starting dispersed particles. So coagulation is best described as a chemical process.
