The purpose of the Weak Acid Dissociation experiment is to determine the dissociation constant of a weak acid experimentally by using acid-base titration with a strong base and stoichiometry. An acid-base titration is a method by which a basic (or acidic) solution of unknown concentration is reacted with an acidic (or basic) solution of known concentration. (1) The pH in acid-base titration is measured using a pH meter or color changing indicator‚ such as phenolphthalein‚ as the known solution is

of cyclic AMP in the tissue : the reaction seems to obey simple saturation kinetics‚ a n apparent intracellular K d for cyclic AMP has been evaluated as 330 nM. The findings are consistent either with a real difference in the intracellular binding constant as compared to that measured in vitro (28 nM) or with the fact that the cyclic nucleotide in the cell may not all be available for the kinase protein receptors. They also suggest that the method described may prove useful for studying any possible

Dissociation is a protective mechanism that stimulates a person to enter into a detached state‚ in which the person is completely separated from his or her usual thought processes and memories. It is a state activated by one’s nervous system upon reaching maximum capacity to process the “real” stimuli around him or her‚ thus causing that person to lose track of time and find another representation of himself to continue in that moment. In “When I Woke Up Tuesday Morning‚ it was Friday‚” author and

Dissociation Model of Prejudice suggests that processing information about others occurs in two-step: the first step triggers the stereotypes automatically‚ and the second step is that people have the control whether to accept the stereotype or not. By this theory‚ people cannot control the acceptances of the stereotype if they are distracted or not paying attention. Dissociation Model gives a cognitive explanation of the source of being

health field there are many types of mental disorders. One that people are not aware: is called dissociation disorder. It is easy to be confused by the multiple definitions of dissociation disorder. It is important to explain the branches‚ types‚ diagnosis‚ and treatment of a dissociation disorder to understand what it is to suffer with a disorder of this severity. The three main branches of dissociation are Dissociative Amnesia‚ Depersonalization/Derealization‚ and Dissociative Identity Disorder (DID)

Objectives The main objective of this experiment was to determine the spring constant using the dynamic method. 2. Theoretical fundamentals On the one hand‚ when a spring oscillates‚ the movement which describes can be classify as a simple harmonic motion. Therefore‚ its position‚ velocity and acceleration equations respect the time will

– The Constant Gardener In the article “The Constant Gardener: What the Movie Missed” by Sonia Shah‚ she talks about the issues and concerns of new drugs being tested on people in developing countries such as Latin America‚ Eastern Europe‚ Asia and Africa. In Shah’s essay she brings up two convincing arguments against these experiments. One argument Shah speaks on is that in the movie The Constant Gardener the seriousness of the possible danger in these experiments is not well depicted. She argues
