Practical 3 Absorption Spectra and the Beer-Lambert Law INTRODUCTION Electromagnetic radiation can be described in terms of frequency (V) and wavelength (λ). Absorbance is the capacity of a substance to absorb radiation and transmittance (the fraction radiation at a specified wavelength that passes through a sample) is physical properties that all molecules have. The purpose of experiment one was to find the maximum absorbance (λmax) occurred for both bromophenol blue and methyl orange by

Recommendation for Mountain Man Beer Company (MMB) Although the launch of a new product is always going to be a risk‚ banking on the withering demand for a single offering is surely not going to alter the fortunes of the Mountain Man Beer Company. More importantly‚ light beer is the largest sales opportunity and it is what the market demands‚ therefore‚ to introduce the Mountain Man Light can be a gateway necessary for MMB to attract new customers and expand its market. Here are a series of recommendations

Brewing Even Better Beer Article Analysis of: Hoppiness is brewing better beer by Julie Corliss 1991. Julie Corliss has worked as a senior medical editor for Harvard Health Publications for the last eight years‚ and she was a staff medical writer for HealthNews‚ and she is a scholar in this field. Julie’s article is about how hops (Humulus Lupulus) and barley (Hordeum vulgare) have dramatically changed the way beer is brewed‚ and how these bittersweet flavors that come from beer change depending on

Introduction: Experiments 1 and 2 main aims are as follows: • To able to use the Beer-Lambert law to explain the relationship linking concentration and absorbance of the coloured solutions methyl orange and bromophenol blue. • To be able to rightly operate a spectrophotometer to assess the absorbance at various wavelengths • To be able to identify the main component parts of a spectrophotometer • To be able to draw a ‘Standard Curve’ from the data collected

absorb certain wavelengths of light‚ and the device will read the others and compare them to the one in the beginning and that’s how the absorption is calculated. With the data obtained from absorption spectroscopy is most often evaluated using the Beer-Lambert Law. This is how absorption measurements are converted into concentration values. The expected outcomes are that we get the concentration of the dye in the sample in this case the orange Gatorade and determine the LD50 of this sample.

Deception Detective How often do people lie? If someone asked you how many times a day you lie‚ what would you say? People most commonly say they lie two times a day‚ this is an understatement. In actuality people lie about seven to eight times a day. Men and women tell different kinds of lies. Men tell self oriented lies‚ which means they tell lies about themselves. Women tell un-oriented lies‚ which means they tell lies about other people‚ specifically lies about other women. Typically

Stone-Age Brew The discovery of beer had several major impacts on early civilizations that are now carried to modern day. To begin‚ early communities found food sources by hunting game‚ fishing‚ and gathering edible plants. These groups were nomadic and didn’t stay in a single location for very long since they had to follow where food was available. However‚ around 12‚000 years ago these people began to settle down and farm instead. These civilizations began to farm cereal grains and barley which
