Formula of a Hydrate
...ples to a lesser value. Next, by the method of trial and error one can distinguish the two unknowns. Procedure: 1. Gather approximately 2 grams of the first unknown and dissolve it with about 10 drops of deionized water. Follow the same procedure for the second unknown. 2. Determine whether the unknown is an acid or a base by using blue and red litmus paper. Acidic solutions will turn blue litmus paper red; Basic solutions will turn red litmus paper blue. Same process for second unknown. 3. Follow the same procedure in determining whether the six samples are acids or bases. 4. In the event that the unknown is acidic, one should only perform tests to the acidic samples. On the other hand, if the unknown is basic then only perform tests on the basic samples. 5. Begin mixing the unknown with each of the 10 solutions and then record the results. 6. With the results of step 3, mix only the corresponding samples. Again, if the unknown is an acid ONLY use the acid samples. Mix the corresponding samples with the same 10 solutions the unknown was mixed with. Compare the unknown with the samples and th...
