Lab O6 – Equilibrium Lab Application Purpose: An introduction to the qualitative aspects of chemical equilibrium. Starting with a reaction at equilibrium‚ one will change the concentration of various ions present in the equilibrium‚ and record the states of the changing equilibrium through observation. Theory: Equilibrium- the point at which a solution has become perfectly saturated; when their forward and reverse reaction rates are equal Concentration- a measurement of how much solute

and answer these questions: A. Which way should the equilibrium shift when HCl is added? How do your results support your answer? It should shift to the left because adding any component causes the equilibrium to shift to the opposite side. B. Which way should the equilibrium shift when Na2EDTA is added? How do your results support your answer? It should shift to the right because the removal of a component causes the equilibrium to shift to the side from which the component was removed

Stephany Matos Chem Lab: Chemical Equilibrium Lab 52 Synopsis Iron (III) ions react with thiocyanate ions (SCN-) to form iron (III) thiocyanate‚ FeSCN2+. It is represented in the equation below: Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq) Therefor the equilibrium constant for this reaction is: KC = [FeSCN2+]/([Fe3+]•[SCN-] For this experiment we were able to determine the equilibrium constant KC for this reaction. First we prepared five different mixtures with known initial concentrations of

Young To begin‚ The Coffee Crisis is about an acute coffee crisis and how it threatens millions of small coffee farmers around the world and is putting economic growth‚ as well as social and political stability‚ at risk in scores of coffee producing countries in Central and South America‚ Africa and Asia. In 2004‚ the governments of coffee producing countries were considering how to respond to the dramatic decline in coffee prices caused in part by a large increase in coffee production in Brazil

Coffee Industry People usually drink coffee to stay up while awake at night‚ besides that many people rely on coffee to get their day started. According to the New England Journal of Medicine‚ “Drinking coffee can lead to a longer life”; however‚ many consumers have no idea of the impact of habits on their coffee and coffee farmers around the globe‚ ethical issues of consumers with the industry is not fair; but to coffee farmers‚ the issues are human rights violations and use of child labor

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

INTRODUCTION The global spread of coffee growing and drinking all started with a curious goat and that’s what legends say. 9th century Ethiopian goat herder Kaldi drank a concoction made from the beans after seeing his energetic goats eat them. The Sufi monks of Yemen in the 15th century were said to drink it as well. During the 17th century when coffee was introduced to Europe‚ the popularity of cafes followed the same pattern as most coffee houses around the world. It quickly became a
