Substances, their transformations and interaction always interested the person. The person is curious by its nature. He needs to know what surrounds him its consistence. At various times people carried out numerous experiments and sought to explain the phenomena which observed. Analyzing results of the experiences, they made hypotheses, created theories, and then checked them by new experiments. So, in such a way appeared new substances, materials. Thus the person learned to be protected and survive, simplified the life. Today each of us daily deals with chemistry, without guessing it at all. In the morning we wash hands and brush teeth. Soap is dissolved in water and forms substance with washing action. The toothpaste neutralizes the remains of acids in a mouth. What can be said about cooking? During the preparation one substances turn into others, having new taste, color, a smell. All these phenomena are explained by science chemistry. The section general chemistry on a site www.freebooksbay.net is useful not only to students and teachers, but also for the ordinary person who wants to know more, about things that surrounds it. Here you can find everything; terminology and the main concepts, information about the most difficult processes, the interesting facts and experiments. For example, Richard E. Bleil in his issue General Chemistry Laboratory Manual affirms that, if all you have is lecture, then it is all too easy to forget that these theories apply to the "real world". The laboratory experience is, by design, your opportunity to see these principles and theories in practice. Thanks to this book you can enhance your understanding of chemistry.
Besides the e-books in General Chemistry here also presented materials in Analytical, Organic, Phisical and Biochemistry. You can be convinced that there is enough material here. Choose the most interesting for you and learn the new world.
