Aims and Objectives of the Experiment

This experiment aims at studying the characteristics of titrations with the strength of different acids used in these titrations. This is done by drawing the titration curves of the different titrations that are carried out in this experiment and interpreting those curves. The units of measurement for this experiment are the standard units that are used in titrations. These are molarity (moles/liter) of substances while the quantities are measured in mL (milliliter).

Theory and Principles

Conductometry is a type of electroanalytical method in analytical chemistry. While other electroanalytical methods use equilibria or electrodes, conductometry is different and employs the conductance of materials ...

Homework Assignment 1

Question 1: Explain the key difference between irritation and allergic contact dermatitis. Contact dermatitis refers to a condition in which the skin becomes sore, red or inflamed after direct contact with a foreign substance. There are two types that include irritant and allergic contact dermatitis. Irritant dermatitis occurs after a body comes into contact with acid or alkaline material. It can also be caused by other materials such as a soap detergent, fabric softeners, solvents and any other chemical that get into contact with the body. The irritation is usually confined to the specific area that the body came ...

Experiment Title

Indication of pH and Buffer Solutions Statement of Purpose Train the preparation of the acetate buffer solution (pH = 4.8) and other solutions. Practice the pH measurements. Test the buffer capacity of the prepared buffer solution.

Hypothesis to test:

- property of buffer solution to keep pH, when the strong acid or base are added; - red cabbage juice acts as a natural indicator, which helps to identify the pH of the solution.

Description of the Experiment

Acetate Buffer Preparation: mix 10 ml of 0.2 M acetic acid with 15 ml of 0.2 M sodium acetate, add 75 ml of distilled water was added. Store in an ...

Electrophilic Aromatic Substitution to yield 4-Bromoacetanilide

Introduction Halogenation is a common process in organic synthesis. It is used in industrial and research synthesis as halogenated compounds are used for numerous widely used goods, including plastics. The lab aimed to perform monohalogenation of acetanilide. The reaction is specific since it is performed without catalyst. The typical halogenation is realized in presence of Lewis acid. Halogens molecules are electrophilic, and do not actively react. In presence of Lewis acid, the interaction is rather active.2 The lab used catalyst-free halogenation. The acetanilide molecule contains the acylated amine. As a result, the electronic density is shifted towards the amine ...

There are various ions that are responsible for the acidic or basic nature of a substance. The hydrogen ions and hydroxide ions are both responsible for the acidic and basic nature of substance respectively. A neutral substance contains equal number of hydrogen ions (H+) as well as hydroxide ions (OH-) An acid is substance that dissolve and donate hydrogen ions leading to more number of hydrogen ions in a solution. A substance that dissolves water and release hydroxide ions is considered a base. A base has more number of hydroxide ions as compared to hydrogen ions hence basic. Alkalinity ( ...

2. The nano carrier needs to remain in suspension in H2O, PBS, human serum, etc. What type of polymer do you need to use to decorate the surface of the nanocarrier to achieve this goal? In order to maintain the nanocarrier in suspension in water, Phosphate-Buffered Saline (PBS), human serum a suitable solution a polymer is needed on its surface. The polymer used needs to accomplish three goals. The polymer needs to decorate the nanocarrier surface to enhance suspension and secondly, to prevent protein absorption. Another characteristic is that the polymer evades the immune system. PLGA poly(lactic-co-)glycolic ...
