January 13‚ 2013 Determining the Concentrations of Red Dye in Sodas Abstract The use of red dye #40 is common in various soft drinks today. The labels on these beverages do not specify how much dye we are consuming. We did this experiment to find out which soda uses the most dye. Using a spectrophotometer‚ we measured how much light is absorbed by various known concentrations of red dye. After collecting this data‚ a standard curve was made that correlated the concentration of red dye #40 to

According to the method selected for developing a solution for the project (p. xx)‚ the next step after the AS-IS analysis is the design of alternative solutions. By following this approach‚ different potential solutions can be created and evaluated. In this way‚ a more holistic problem solving process can be achieved‚ and the broader perspective obtained‚ and eventually the best alternative selected‚ when compared to designing only one solution and hoping it will solve the problem. All the benefits

2013 Determining the Mole Ratios in a Chemical Reaction Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to determine those ratios. During this reaction‚ hypochlorite

Determining Effective Orientation and Training Methods When one thinks of the word “training‚” what comes to mind? [Writing suggestion: Unless in a quote or a title‚ avoid rhetorical questions in academic writing. A good idea is to provide answers‚ not questions] Teaching‚ conditioning‚ practicing‚ and building are a few words to explain it. It goes much deeper than that though‚ and it is necessary during the life of employment

A variety of procedures are used by psychologists to study the functions of different areas of the brain. Some of them are very old methods and outdated; some of them are most recent in origin and frequently used by modern investigators. The methods help us to study the localization of the functional areas of the brain. One of these methods is the stimulation method. A specific part of the brain may be stimulated either by electric current or by chemicals. Through electrical stimulation‚ we can

A Lab 10.2 Determining the Concentration of Ammonia in Window Cleaner Solution Design (D) Aim To determine the concentration of ammonia‚ NH3‚ in the commercial window cleaner solution Background Window cleaner contains ammonia‚ NH3‚ a weak base‚ which helps remove dirt from glassware. The concentration of ammonia in the window cleaner solution varies by brands. Titrating the window cleaner solution with an acid of known concentration allows us to calculate the concentration of the ammonia

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister
