The formed precipitate may stay as a suspension in the solution if there isn’t sufficient gravity. The low temperature reduces the solubility of salts, causing them to precipitate in the solution. In addition, precipitates can form when the temperature of the solution is lowered. The chemical species that cause this precipitation is called precipitant. Then these ions can react with each other to form a precipitate or stay as a solubilized ion in that solution. Soluble ionic compounds can break into their ions in the solution. A precipitate is formed when two soluble ionic compounds are mixed. Precipitation is the formation of an insoluble molecule in a liquid solution this insoluble molecule is called the precipitate. If the wrong blood group is given, it will cause clump formation of red blood cells since antibodies react with the blood cells, forming in clumps. This is very important in blood grouping because the matching blood group should be given to a person in blood transfusions. The best example for agglutination comes from biology, in the formation of visible aggregates of antibody-antigen complexes. Agglutination occurs with particles which are already present in the solution. This mass will either stay as a suspension or will sink to the bottom of the container. Key Terms: Agglutination, Aggregate, Blood grouping, Precipitation, Precipitate, Precipitant, Solution What is Agglutination?Īgglutination is the aggregation of particles to form a single large solid mass. What is the difference between Agglutination and Precipitation The main difference between agglutination and precipitation is that agglutination is the formation of a solid mass by aggregating suspended particles in a solution whereas precipitation is the formation of a solid mass as a result of a chemical reaction that occurs between two ionic components. However, it is insoluble in that solution. This formed solid mass will either stay as a suspension or sink to the bottom of the container if it is denser than the solution. Main Difference – Agglutination vs Precipitationīoth agglutination and precipitation refer to the formation of a solid mass inside a solution.
