nitrogens on this station. Both of these methods rely on the repulsive electrostatic interactions between the positively charged axial component and the post-switching cationic nature of the benzidine station (Figure 5.4). Deuterated trifluoroacetic acid (d-TFA) was added in the solution which resulted in the protonation of the benzidine residue and shuttling of macrocycle in to the biphenol station of the Rotaxane. This was supported by NOESY 1H NMR that showed a shift in the peaks in retrospect to

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

Industrial Separation Blood is a liquid mixture that is found in the biosphere in humans and animals. Blood is always red in appearance‚ liquid‚ and can be thick or thin in texture. The major products of blood are blood plasma‚ white blood cells‚ red blood cells and platelets. Blood has a vital role in our day to day lives and makes it possible for life as we know it as its functions are key to our survival. Blood transports oxygen and carbon dioxide around our body‚ moves nutrients‚ waste products

Black children were also excluded/denied access to common schools and Mary Bibb wanted to change this‚ making

Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid)‚ a phenol (p-tert-butylphenol)‚ and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent‚ the solution that contains these dissolved compounds is called an extract (Manion
