Is Gelatin a suspension?

Yes
Gelatin is not considered a suspension but rather a colloid. A suspension consists of solid particles dispersed in a liquid, and over time, they settle at the bottom. In contrast, gelatin is a colloid, which means it forms a stable mixture with a continuous solid phase (gel) dispersed within a liquid phase. The gelatin molecules form a network-like structure throughout the liquid, giving it its characteristic semi-solid or gel-like consistency.
To determine whether gelatin is a suspension, we need to understand what a suspension is. A suspension is a heterogeneous mixture in which solid particles are dispersed, but not dissolved, in a liquid or gas.
Now, let's consider gelatin. Gelatin is derived from collagen, a protein found in animal connective tissues. It is usually obtained from animal bones or skin. Gelatin is typically available in the form of a powder or in sheets. When gelatin is mixed with liquid, it forms a gel-like substance through a process called gelation.
Gelatin can be considered a suspension because it consists of dispersed solid particles (protein molecules) that are not dissolved but rather suspended in a liquid mixture. When gelatin is mixed with liquid, the protein molecules aggregate and form a structured network, giving the mixture its characteristic gel-like texture.
So, the answer is yes, gelatin can be classified as a suspension based on its structural characteristics.
