Dissociation constant

Questions 1. Why are three replicate titrations done for each sample? Three titrations are performed because an error may occur in one of the titrations and getting two extra titrations can help eliminate the wrong answer. It is also a great way to practice accuracy and precision. 2. What other household products could be analyzed by titrations (suggest three)? Some other household items that could be analyzed by titrations are fruit juice, Cola beverages and household ammonia. 3. Why is it…

Bisoprolol fumarate. These may indicate moderate kinetics of complexation between Vildagliptin with Bisoprolol fumarate. The value of stability constant for the drug-drug system at pH 1.0, 3.0 and 6.8 are 1.875 0.7778 and 1.2000 respectively. At pH 1.0 it is found that Vildagliptin form relatively stable complex with Bisoprolol fumarate (stability constant 1.875) is high in comparison to pH 3. From the IR report it…

Buffers are substances that help reduce the changes in concentrations of ions which are known as hydrogen ions and hydroxide ions. The composition of a buffer in an acidic aqueous solution is combined containing a weak acid and salt of conjugate base of the weak acid. (Importance of Buffers, 2013) The composition of a buffer in a basic aqueous solution is combined containing a weak base and a salt of conjugate acid of weak base. A buffer solution resists the changes in pH therefore resisting…

With this experiment intend to prove Salem Lakes ability to buffer chemicals used in the water treatment process versus that of the Yadkin River. Using a jar test machine, simulated the addition of an acid in the form of Al2SO4, and a base NaOH to the coagulation process. Salem Lake does show a preferred buffering at higher acid doses, though Yadkin River is more efficient at the low to mid-range dose. INTRODUCTION There is a distinct difference in the buffering capacity of Salem Lake versus…

It has been said that women are more likely to be sexually abused as a child or at a young age rather than men. However males that have been abused in any way may experience pathological dissociation. The average number of alternate personalities a person with DID has is between the numbers of eight and thirteen years of age. But there have been cases of more than 100 different personalities within an individual with DID. I searched quotes…

As many psychologists suggest, the human brain is largely a product of its experiences from birth until death. In its conception until its conclusion, the brain comes full circle. It begins building itself up from nearly nothing and eventually degrades until it becomes nothing yet again. During its period of somethingness, it is an original invention, built by the unique experiences of the human it directs. As a by-product of both positive and negative experiences, the brain uses specific…

Defining Normality What really is considered to be normal? What is 'normal ' depends on the point of view, beliefs, and opinions of each person. In order to help scientists consider what is normal and abnormal, there are six general approaches when trying to establish the differences between normal and abnormal. Sociocultural What a person or group of people does in one culture (whether it be traditional, compulsory, etc.), it may not be considered acceptable towards people of another culture.…

An individual's negative historical experiences doesn't always motivate them to become evil, it sometimes causes a trauma so great that it generates mental illness within the victim and causes dissociation. This is evident within the characters Sanjay Singhania in the film Ghajini and the character Teddy Daniels within the film Shutter Island. Sanjay Singhania was once one of the most wealthiest businessmen in India until an event left him mentally disabled. One night, Sanjay was going to his…

According to the DSM V, the diagnostic criteria of Dissociative Identity Disorder, also known as DID, are the following five things. First, Disruption of identity characterized by two or more distinct personality states, which may be describes in some cultures as an experience and possession. The disruption in identity involves marked discontinuity in senses of self and sense of agency, accompanied by related alterations in affect, behavior, consciousness, memory, perception, cognition, and/or…
