Flame Reports Samples For Students

Abstract

This experiment sort to find an accurate and most viable method that would be used in laboratories to the measurement of iron concentration in aqueous samples. The methodologies that were identified for further analysis included; colorimetric assay (molecular spectroscopy), flame atomic absorption spectroscopy, redox titration (volumetric) and cation exchange chromatography (EMA technique). These methods were analyzed of their advantages and later subjected to a validation test. In the process, a wide range of CRMs were used alongside six other samples that contained unknown iron concentration.

The experiment was thus, geared towards providing answers to statements like; the necessity of quantification of ...

It looks into the conditions of the burnt house specifically the areas close to be the possible cause of fire: A malfunction in the electrical system of a Christmas tree. Also, it examines possible reasons and tries to explain the events leading to the fire; its cause, origin, fuel and fire patterns left in the house. The conditions of the house after the fire are carefully examined so as to eliminate possible and suspected ...

Exercise 1: Determining the Caloric Content of Three Foods

Abstract:
In the beginning, I collected all the equipment that was required. After that, I emptied the balance and set it on zero and then, mass of the empty beaker was measured. Then, I added 50ml water into the empty beaker and checked the mass on the balance again. Afterwards, I take a foil paper and placed it at the bottom of the burner stand, and then I put the beaker containing the water on the stand for beaker. The initial temperature of the water was measured firstly, and then, I took a marshmallow and measured its weight with and ...

After gaining permission from the property owner, a fire investigation was launched concerning the context of this situation. The objectives of the probe included an establishment of the origin of the fire and a determination of the most probable ignition sources. An understanding of the circumstances involved in this case was important as an initial step towards the prevention of future fire incidents. The significance of identifying the ignition sources was to enable the property owner to sensitize the occupants on the same.

Description of the Incident

Regarding this case, a fire occurred near a disposed container of flammable liquid. Next to this ...

Report

A successful application by homeowner to have the cause of fire investigated and determined has led to this inquiry to unravel the cause of the fire with a future anticipation how homeowners can avoid fire accidents. This report will also identify some of the potential common causes of fire accidents at home to enable the owner inform relevant people who can help seal loopholes that are likely to contribute to devastating effects of fire accidents.

Description of the Incident

The main door leading to the kitchen reveals how the fire stated. In the cooking area, there are two relatively heavy wooded cupboard position ...

In this assignment, food analysis involves involve several procedures that have been used to identify the various methods with which the fats, salts, ash and moisture in food are subjected to different conditions to produce results. Several methods have been used with a combination of different solutions that have been able to produce different results. Therefore, this report would include several methods that were applied on fats, salts, ash as well as moisture in food. For instance, soxhlet method would be used in the determination of fat content in foods, Mohr method was used to determine the amount of salt ...

Arson is the crime that involves setting fires to buildings, vehicles, forest or wild land areas, or peoples’ other properties either intentionally or with deep-seated malice (Swanson et al, 2012, p. 510). A person who engages in such a malicious act is called an arsonist, and their intention is normally to damage property. It is distinguishable from other causes of fire such accidental electric fires on buildings or natural wildfires that erupt in forested areas due natural causes. The main differentiating aspect of arson is that, a person deliberately sets fires on property owned by others to destroy it, or owner ...

Purpose

Materials and Methods
Gram Stain: the test was done to differentiate Gram-positive from Gram-negative organisms. A drop of the unknown 300 was suspended on a slide and the culture spread to an oven thin film. The culture was air dried and fixed over a gentle flame. Crystal violet stain was added over the culture and allowed to stand for 60 seconds. The stain was poured off and rinsed gently. Iodine solution was added on the smear, allowed to stand for 60 seconds and the stain poured off. The slide was rinsed with running water, and a few drops of decolorizer solution ...

Introduction

Bacillus Subtilis are the organisms that are aerobic, Gram Positive, spore-forming belonging to the Bacillus genus. The organisms are together with other species that are closely related play a crucial role in disease, food poisoning as well as food spoilage. Lack of methods that are standardized for the identification of the organisms whether coming from the food or environment has made the tests to be difficult. Use of morphological as well as physiological tests have offered the best ways to identify organisms in the laboratory although there are inconsistent and lack of reliance in these methods.
Identification of an ...
