A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

Introduction The Gram stain is one of the most useful staining procedures in microbiology . It is one of three differential staining techniques‚ is used to identify divide bacteria into two groups: Gram-positive bacteria and gram-negative (Madigan‚ Martinko‚ Dunlap‚ Clark (2009). These staining reactions take advantage of the fact that cells or structures within cells display dissimilar staining reactions that can be distinguished by the use of different dyes (Brown 2009). A gram positive bacteria

Stoichiometric Analysis Formal Lab Report I. Purpose- The purpose of this lab is to show stoiciometric reactions and relationships first hand. It also increases our level of understanding about the complicated relationships in chemical reactions and in stoichiometry. II. Introduction- In chemical reactions and formulas there are various relationships between masses of reactants and products. The study of these relationships is called stoichiometry which is derived from the Greek words stoichein

of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion is present in the K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O using

Bio Lab Report Title: Gram-Negative and Gram-Positive contamination in yogurt. Introduction: There is bacteria that is beneficial and harmful in the human. Yogurt was choosed to be the best example that contains this bacteria. What happens to be the difference between these two types of bacteria‚ and how are they harmful? The bacteria is considered “Gram-Negative‚” and the substance is considered contaminated when there is more negative bacteria than positive bacteria. This will prove or disapprove
