Webprecipitation reaction. Formation of an insoluble compound will sometimes occur when a solution containing a particular cation (a positively charged ion) is mixed with … WebDuring synthesis, the reaction mixture is heated up to 120°C after the addition of urea. During this time, the color of the reaction mixture became darker from light brown to dark brown and the mixture dried up until the volume of the reaction mass suddenly increased and consequently caught fire by itself. Then the dark brown fluffy mass is
