Discussion/Conclusion The three metals obtained in this experiment have many potential uses as solids. Silver Chloride has many practical applications, including being used for photographic paper, bandages, and wound healings products, and is known an antidote for mercury poisoning. Aluminum Hydroxide is often used as a fire retardant filler for polymer applications. Lastly, Barium Sulfate has many applied employments, ranging from being used clinically as a radio-contrast agent for X-Ray imaging, to pigmentations in oil paints, and can even be utilized as a catalyst support for selectively hydrogenating functional groups sensitive to over-reduction. In this experiment, the three metals can all be re-used commercially and do not need to be discarded as waste. In order to ensure all of a particular metal was recovered as a solid,

Unformatted text preview: the techniques of centrifuge, filtering, and evaporation can be used to separate the components. As a precaution to ensure that solid was fully recovered during the experiment, the gelatinous compounds in reactions one and two were initially centrifuged then filtered twice to obtain as much of the solid as possible. For the third reaction, the products were simply filtered twice to ensure maximum separation. Possible errors during the experiment include not obtaining a correct amount of each sample. When isolating a solid, it can be difficult to obtain the full sample. At times, the solid can be left over in a test tube and can even travel through the filter. Also, it is difficult to weigh the mass of an isolated compound because it is gelatinous....
