General chemistry laboratory

Well my subject for this semester is the laboratory of geneal chemistry.   I enjoy it very much this semestrer because the last semester i did not have any practical course so i am very excited.

In the laboratory we make differents experiments as the preparations of cristals in based of copper sulphate, and the idea was that after the a week will meet  with large and beautiful blue crystals, but the reality was that I only found small balls in my jar, which did not seem at all to what was wanted.

 Other practice that enjoy very  much was when  in which some halogen species 

could be identified through the color change of the solution by an oxidation process, 

this practice was very funny and dynamic, I learned very much.  In the last laboratory 

was of pH, it was a good practice because  all the theoretical calculations were correct

 with respect to the expected pH, reason why it was very interesting to achieve

 the interaction between the theoretical and the practical.
