👉 Undispersed, also known as undissolved or undispersed, refers to a substance that is not dispersed or mixed with other substances. It means that it does not flow or float in water, air, or any other medium and remains solid, liquid, gas, or plasma-like. In chemistry, the term "undispersed" is often used in describing a solution where there are no precipitates (or aggregates of particles) formed when dissolved solutes combine with each other.
