Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial

Best segment is freedom lovers. The Ford Ka was scheduled for launch at the Paris Motor Show in October 1996. But Brand Manager‚ Gilles Moynier‚ needed to decide on the target market for the new product. The car industry was traditionally segmented into size tiers‚ but Europe’s market for small cars was changing rapidly and even alternative segmentations did not reveal a clear target for the Ka. This case introduces students to the fundamental marketing problem of market segmentation and target

Acetylsalicylic acid is the active pharmaceutical ingredient in aspirin and can be synthesized by the esterification reaction of salicylic acid and acetic anhydride in the presence of an acid catalyst. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. When heating the salicylic acid mixture in the warm water bath‚ the mixture should be removed from the bath within 8 minutes‚ to reduce the chance of the acetylsalicylic acid decomposing

# 4: Dissociation Constant Weak Acids Introduction: The dissociation constants of weak monoprotic acids were determined with the aid of a buffer and pH meter. Experiment: This experiment was performed according to the procedures as provided in the Chemistry 111B laboratory manual: Po‚ Henry and Senozan‚ N. "General Chemistry Experiments Chemistry 111B"‚ 8th Ed.‚ 2004 Hayden-McNeil Publishing‚ pp 80-88. To determine the dissociation constants of weak monoprotic acids (HX and HY)‚ a buffer was needed

final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore

That might be the reason why‚ despite its innovative styling attributes‚ Ford Ka could not alter consumer perceptions of what a small car can offer to the extent the Renault Twingo did. Cost
