· Agitation is the process of keeping a mixture that has been mixed in the proper mixed state required for the ''end'' product. Mixing refers to the actual stirring of different liquids and/or materials to blend them together into an end product or mixture. Once this mixture is ''mixed'' it may require agitation to keep the mixture in the proper ''mixed'' state.
