Essays on Crystal Violet

Introduction

The kinetic characteristics are important for the design of chemical engineering processes. They allow assessing the time required for the reaction and choosing the temperature range suitable for the reaction. The reaction path is observed by measurments the transmittance of the Crystal Violet solution that reacts with sodium hydroxide. The concentration, and the color of the solution changes with the reaction flow, and this is measured by the spectrophotometer.

The data are plotted as concentration - time and logarithm concentration time, and the reaction rate is:

Rate = [Crystal Violet] [Sodium Hydroxide]. Using the excess concentration of one of the reagents, the reaction rate with respect to the other reagent is found from logarithmic plot (Rahul & Chakrabarti ...

Microbiology is the study of microorganisms. Microorganisms are those organisms that are less than a millimeter in size and require the help of a microscope to view them. Microorganisms can be unicellular or multicellular but have very simple cell structure, unlike the highly developed, complex organisms such as larger animals and humans. Microorganisms are classified based on criteria such as their cell structure, pattern of growth, nutrition, reproduction method, etc. However, microbial classification is a challenging task due to the dual nature of some microorganisms that exhibit both animal and plant like characteristics. Some microorganisms are photosynthetic like plants but they also ...

Staining is used in different streams of biology to study cells and tissues. It is a process in which dye is added to better visualize the cells under the microscope. Staining is needed because it is difficult to view cells under a microscope or to differentiate one type of cell from another. The dyes used help in outlining the cells or its organelles or in highlighting the cytoplasm and make them standout as compared to the background. This helps in identifying as well as counting them. Different stains can also be used to differentiate between two types of cells or even ...

The process of identifying an organism involves the determination of where an isolate or an organism needs to be placed within a group of organisms that are already known. The process is usually done to conform to a given scheme of classification. Most of the microorganisms that may be found in the environment require to be identified aiming at identifying the different species that may be found in a given environment. The identification enables physicists and health workers to associated different sources with different organisms especially those that cause diseases. Organism classification may also help in the diagnosis of different disease by ...

UNKNOWN #16

SUMMER 2013 INTRODUCTION Purpose The purpose of the lab is to separate characterize and identify microbes from unknown mixed culture using the morphological and biochemical methods.

Theory

The process of identifying bacteria is a systematic and careful process which uses various techniques to narrow down the bacteria types which are present in an unknown culture of bacteria. This process produces advantages for many factors of research of microorganisms and assists in the proper treatment of patients (Aneja 10). Several tests were performed to give the fermentation abilities, availability of specific enzymes and specific biochemical reactions.

The Data Quality Objectives (DQO Process) is a planning process that has been developed by the United States Environmental Protection Agency. This particular planning process is used when environmental information or data is used to make a choice between two specific alternatives or to make a derivation of contamination estimate. The process is also used in the development of acceptance and performance criteria that find use in the clarification of study objectives, defining of appropriate data type and the specification of potential errors of decisions that are then used as the basis for the establishment of the quantity and the quality of ...
