Humic acid

this lab was to separate unknown compound 204, composed of an amine, a carboxylic acid, and a neutral component, into each of its three respective states. The unknown compound was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in separating reactants and…

Aim 1: Determine the amino acid sensing specificity of folliculin. Since folliculin’s has novel molecular function in amino acid sensing I plan to further understand whether FLCN specifically senses a certain amino acid and if this level of detection is enough to elicit an mTORC1 response. 1.1. Determine if folliculin’s novel molecular function in amino acid sensing is triggered by glutamine. mTORC1 activation by amino acids requires FLCN, whereby its lysosomal residence during starvation…

state. It was indicated that PANI nanoparticles structure has an average diameter of 50nm, while PANI nanorods structure was found to have an average length of 4µm and average diameters of 95nm. The effect of the PANI morphological structure on the Acid blue 25 dye decolorization process was studied. The PANI nanorods recorded higher rate of dye decolorization of 99% within 8min compared with PANI nanoparticles that recorded the same percentage decolorization within 16min. Keywords:…

2.2. Extraction process analysis The solvent is fed from the bottom and broth from the top since the mass separation agent or solvent has a lower density than the aqueous mixture. The raffinate phase contains most of water and traces of HAc, and solvent, whereas the extract phase includes most of the solvent, HAc, and traces of water. The amount and composition of the mixed solvent significantly important for the process economy because it directly affects the composition of HAc in the extract…

determine pH levels of various substances using different methods. Two techniques were used, the pH paper indicator and the pH meter. Out of ten substances that were used, five of them were found to be acidic, namely: hydrochloric acid, coke, toothpaste, milk, and acetic acid. Sodium hydroxide, buffer solution, bleach, and the detergent were found to be basic. Bottle water was found to be neutral. Substances are said to be acidic because of having pH levels lesser than 7, and those having pH…

Purpose The purpose of the experiment was to see the effects of combining certain solutes and solvents. By conducting this experiment it is seen how solutions and mixtures relate to the six postulates of particle theory. When conducting this experiment, the particle theory was thought of, such as when you mechanically agitate a solution, particles move around and bump into each other, breaking up. The specific substances will be stated in the hypotheses. There were many things looked for when…

Introduction: A chemical reaction occurs when you mix baking soda and vinegar. The type of reaction that occurs when you mix the two is called a chemical reaction, the chemical property that is used is called reactivity. Some of the evidence that proves that a chemical change is occurring is when you start to hear a sizzle sound and gas starts to be produced. When the gas starts to produce you will see the bubbles start to rise. The two types of matter that are creating this reaction are called…

Part 1 - Making the solutions of the citric acid samples. Rinse all the apparatus very well before using them in the experiment while performing any step. To make the samples we need to take the sample and add distilled water to it so that there is decent amount of sample made for performing the experiment. The ratio of distilled water to the sample solution (pure) is 1:1. [Note: there wont be any change in the molarity of the sample as we are just increasing the volume by adding distilled…

Lab 14/ Test 6: Determination of Acid Dissociation Constants through Titration Sabrina Tom I.Abstract The two unknown solutions A and E were titrated with NaOH solutions. For each solution, one fast and three slow titrations were done to see where the pH rose exponentially. The unknown solutions A and E were determined to be Pyridinium ion acid and oxalic acid, respectively. II.Theories One significant concept throughout this lab is titrations. A titration is a lab method analyzes a…
