Awater supply has been contaminated with an unknown mixture of toxic metal solutions leaking from a nearby factory. one way to treat the problem is to precipitate the metals from the water. environmental chemists are considering using sodium carbonate and sodium sulfate for this purpose. based on the solubility table, which compound would you recommend?

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
