**Fracking and Radioactive Wastewater Management**Fracking operations generate radioactive wastewater along with solids contaminated with radium. To manage this waste effectively, the solid and liquid phases are initially separated. The solid waste is then disposed of in a landfill. The next step involves treating the wastewater to precipitate radium out of the solution, allowing the solid and liquid components to be separated and ensuring that the resulting water is free of radioactive elements.**Question 7: Precipitation of Radium Ions**Which of the following would be the best choice for the precipitation of radium ions (Ra²⁺) from water?a. NaNO₃b. K₂CO₃c. Mg(HCO₃)₂d. Li(C₂H₃O₂)**Question 8: Chemical Reaction**Write a balanced molecular equation for the reaction of RaCl₂ with your chosen compound from Question 7. Make sure to include the state of matter for each compound involved in the reaction.

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. Since no precipitation occurs, the solution is supersaturated. The reaction is: heat + sodium acetate (s) + H2O (liq) <---> sodium acetate (aq). If you disturb the supersaturated solution of sodium acetate, which of the following statements is true? b. Solid sodium acetate will precipitate if there is enough water present. c. Solid sodium acetate will precipitate if there is not too much water present. d. Nothing will happen. The system is at equilibrium. e. Solid sodium acetate will precipitate and the solution will get warm.

The two solids CuBr(s) and AgBr(s) are only very slightly soluble in water: Ksp(CuBr) = 4.2 × 10-8and Ksp(AgBr) = 7.7 × 10-13. Some CuBr(s) and AgBr(s) are both mixed into a quantity of water that is then stirred until it is saturated with respect to both solutes. Next, a small amount of KBr is added and dissolves completely. Compute the ratio of [Cu+] to [Ag+] after the system reestablishes equilibrium.
