Solid aluminum nitrate is slowly added to 150 mL of a 0.0699 M potassium hydroxide solution. The concentration of aluminum ion required to just initiate precipitation is M.the expert working on my last question, doesnt have to anymore, its been answered thanks.
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,CO3 c. Mg(HCO,)2 d. Li(C,H,O2) 8. Write a balanced molecular equation for the reaction of RaCl, with your compound of choice (your answer from the previous question). Include state of matter for each compound in the reaction.
