The beginning of the lab contained a substantial amount of information detailing what chemical properties make up the structure of a salt hydrate. It provided essential knowledge proceeding to the successful completion of this lab such as the idea that hydrates are salt compounds which have formed weak bonds to water molecules that can easily be broken through the use of heat. With this information in mind, it was expected that a series of procedural guidelines following this information be used to aid in the identification of the chemical change taking place as one of the 2 following chemical formulas:
BaCl2 + 2H2O (s) BaCl2 + 2H2O (g) BaCl2 + 2H2O (s) BaO (s) + 2HCl (g) + 2H2O (g) Based on the information given to us in the preliminary portion of the lab, it is easy to identify whether the heating of the hydrates will result in either a release of solely water vapors or water as well as acidic vapors. With the 2 chemical equations written above it is easy to make a scientific prediction of …show more content…
It is indicated throughout the information in the original information stated at the beginning of the lab that there are only 2 options for what a hydrate’s chemical equation will indicate. Either acidic vapors are released or not. In testing the 4 other vapors, it was discovered that 1 releases acidic vapors almost instantly, 2 took a second heating before the acid could be picked up by the litmus paper, and the final 1 had no release of acid at all. Like the first portion of the procedure, there is room for error. The observations taken throughout the lab showed that each hydrate had a different reaction to being heated which altered its appearance in a particular way. Their chemical equations vary is subtle ways, and human error still plays a key role in what may potentially be skewed
