Lab Report To A Buret

The first flask was placed under a buret. Finally we titrated the KHP by adding the base until the end point was reached, which was when it turned pink completely. We repeated this twice and then cleaned up. The procedure does not include very difficult math, however the calculations did. The harder math calculations included finding moles of the acid, moles of the base that was used to neutralize, and the molarity of the base. After all calculations, below is what we concluded. The molarity you had to be careful with because it was moles/liters and our readings were in milliliters so we had to convert first. In conclusion, even though the lab procedure is not about moles, most of the calculations are and this is one lab where the concept of
They stated:”This law states that, despite chemical reactions or physical transformations, mass is conserved—that is, it cannot be created or destroyed—within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants”. This basically means that how much you start with has to be equal to how much you end with. This ties in with the different types of chemical reactions and how you can predict the products for the reactions. Jack Brubaker explained in an article he wrote titled How to Predict Products in Chemical Reactions that the first step is to identify the type of reaction it is. For example, if the compound is first and then it shows the arrow and then the individual components you would know its decomposition. Basically, you analyze what they are giving you and you use a reference to try and figure out the type, and then follow the steps on determining a product. I think the POGIL we did, called Types of Chemical Reactions explained it very good, even if it was difficult to comprehend because they really walked you through it. The first page of the packet gave you a section of different equations and you had to choose from four different types, which kind of reaction it was. On the next page, the first thing was to match a description with what kind of reaction it was. This was really helpful because you could physically see in words what each reaction meant. On the next page, it gave you equations and you had to identify which kind it was again. Throughout the way, there were questions to be answered and you had to really think about them because you had to provide examples. The purpose of the POGIL was not to predict the products, it was more based on determining the kinds of reactions. However, doing a whole packet on that, made it very easy to memorize how to
