A reaction in which some soluble salts are added in a solution and precipitates are obtained, is called a precipitation reaction. The precipitates are formed by insoluble salts formed as a result of the reaction.When radium ions are present in water, they exist as aqueous ions. The carbonates salts of alkali earth metals are less soluble in water, while nitrates and bicarbonates are more soluble. The salts of radium with carbonate ions are insoluble in water. When potassium carbonate is added to water, the radium will react with carbonate ions and forms radium carbonate, which is insoluble in water. If salt is insoluble in water, it comes as a precipitate in the solution. Hence, potassium carbonate is used to precipitate out radium ions.The required reaction is- the molecular equation of RaCl2 with K2CO3 is as follows-RaCl2aq+K2CO3aq→RaCO3s+2KClaq

Fracking produces radioactive wastewater as well as solids contaminated with radium. To treat this waste, the solid and liquid phases are first separated, and solid waste is put in the landfill. Next, the wastewater can be treated so that radium precipitates out of solution. That way, the solid and liquid can be separated and the water will no longer contain this radioactive element. 7. Which of the following would be the best choice for precipitation of radium ions (Ra*) from water? a. NaNO, b. K,CO, c. Mg(HCO,), d. Li(C,H,O,)

When we discussed LeChatelier's Principle, we discussed the concept of supersaturated solutions. A supersaturated solution is prepared when sodium acetate is dissolved in hot water at around 80 deg C, and then the solution is cooled to room temperature.
