Table 4.2.2 gives guidelines for predicting the solubility of a wide variety of ionic compounds. An x-ray of the digestive organs of a patient who has swallowed a barium milkshake. A barium milkshake is a suspension of very fine BaSO4 particles in water; the high atomic mass of barium makes it opaque to x-rays. And so whatever the precipitate would be, it would not involve those said the the remaining possibilities would be silver with the chloride or silver with the bromide. Figure 4.2.2 Outline of the Steps Involved in Producing a Black-and-White Photograph. The potassium and bromide ions would remain in solution because potassium bromide is highly soluble. In aqueous solution, aqueous ammonia forms equilibria with gaseous ammonia and ammonium. The likely outcome here is that ammonia gas would be vented from the reaction vessel and the amount depends on the concentration and amount of solutions used. A piece of solid zinc is dropped into hydrochloric acid solution. Both mass and charge must be conserved in chemical reactions because the numbers of electrons and protons do not change. You dissolve a 10.00 g sample in water, oxidize it to arsenate, and dilute it with water to a final volume of 500 mL. A silver halide precipitate forms ranging in colour from white (silver chloride), to cream (silver bromide) and yellow (silver iodide).
