Lab 6.1 Double Replacement Reactions

In our lab we looked at many different scenarios where a double replacement reaction either resulted in no apparent change, or the formation of a precipitate.

First, take a look at your predictions. Where they all accurate? If not explain which ones did not match up. See if you can figure out what happened. There was one trial that had results that did not match up with the expected prediction. Where you able to find it, which one was it? What do you think the insoluble product was, this will go against what table F tells us!!

Write a procedure on how to write a double replacement reaction. You can do this with bullets or paragraph form. The steps that you must have include: finding and writing the formulas for the products, balancing the reaction, and finding the precipitate. Describe theses steps (and more if you need them in detail, don't just give me a list of what I just gave you!!)





Precipitation reactions are very important in water treatment and purification. Find a contaminant that is removed from waste water before it is processed back into nature using a precipitation reaction (hint do a google search). See if this reaction is consistent with the information on Table F (it depends on the ion that is used). Sulfate is an ion that is often used to form precipitates, using Table F why is this a good choice.
