Micro-Reactions: Predicting the Products of Double Replacement Reactions

Introduction – A double replacement reaction is a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound. If you have the reactants of two reaction solution that you can determine the products. All you need to do is pair the positive parts of the compounds with the other compounds negative part. Once you find the products you can determine their phase of matter by using Table H. You can also use Table F to determine the solubility guidelines for aqueous solutions. If the product falls under soluble or exceptions to insoluble it is in the aqueous stare. If the product falls under

If the product/reactant falls under insoluble or the soluble exception column it is a precipitate. You can identify a precipitate in a reaction if the reactant or product is in solid form.
6. Balanced equation and state:
a. No Reaction
b. NaOH + CuSO4 --> Na2SO4 + Cu(OH)2 (s)
c. 2Na3PO4 + 3CuSO4 --> 3Na2SO4 + Cu3(PO4)2 (s)
d. NaCl + AgNO3 --> NaNO3 + AgCl (s)
e. NaOH + AgNO3 --> NaNO3 + AgOH (s)
f. Na3PO4 + AgNO3 --> NaNO3 + Ag3PO4 (s)

Conclusion – The main idea of this experiment is that if you have the reactants of a double replacement reaction that you should be able to find out several things. First, you can figure out the products from switching the positive ion with the other positive ion. Once you have found the products you can determine the phase of matter they are in from Table F and H. Finally, you can also determine whether the reaction went to completion or not. The observations and data above leads me to believe that our experiment is valid. We were very careful and observant of the directions that needed to be taken. Once source of error could have been that certain substances were placed in the wrong wells, causing your data to stray from the correct information. One way this experiment could be applied to a real life situation is he residue in the bottom of a glass in your bathroom. There is stuff dissolved in water, and any trace of water left in a glass will eventually evaporate and leave the residue.
