The Equilibrium Constant of an Ester Hydrolysis Reaction CHM 152LL Section 33263 March 28‚ 2014 John Weide Abstract: The purpose if this experiment is to determine the equilibrium constant of an unknown alcohol. In this experiment unknown alcohol number three and unknown ester number three were used. The equilibrium constant was found by titrating a series of reactions containing H2O‚ HCl‚ and the unknown ester with only the last solution containing the unknown alcohol

Spectrophotometric determination of Ascorbic acid Concentration in an Unknown Solution Introduction: The naturally occurring organic compound with antioxidant properties is Ascorbic acid shortly referred as (AA). Normally the color of Ascorbic acid is white‚ but in some cases of impure samples it appears yellow in color. Ascorbic acid is solid in state. In water it dissolves well to give mildly acidic solutions. Ascorbic acid is one form ("vitamer") of vitamin C [1]. So‚ Ascorbic Acid (AA) in other

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.

Argumentative Fallacies "Writers of argumentative essays must appear logical or their readers will reject their point of view. Here is a short list of some of the most common logical fallacies--that is‚ errors in reasoning. Check your rough drafts carefully to avoid these problems. "Students sometimes ask‚ ’If a logical fallacy works‚ why not use it? Isn’t all fair in love‚ war‚ and argumentative essays?’ The honest answer is maybe. It’s quite true that speakers and writers do use faulty logic

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

Standardization of NaOH and Determination of Unknown Acid KEYWORDS: quantitative analysis‚ titration‚ buret‚ endpoint‚ standardization‚ half-equivalence point‚ calorimetric titration‚ potentiometric titration ABSTRACT: The concentration of sodium hydroxide was determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration

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)
