A suspension is a mixture in which small particles are dispersed throughout a liquid or gas but are not dissolved. Over time, these particles can settle at the bottom if left undisturbed. Common examples of suspensions include muddy water and orange juice with pulp. In a suspension, the particles are usually larger than those found in solutions, making them visible to the naked eye. Unlike solutions, where the solute is completely dissolved, suspensions require stirring or shaking to keep the particles evenly distributed. This property is important in various applications, such as in pharmaceuticals and food products.
