Amperometric titration

Acid Base Balance Study Guide Definition: The body’s ability to regulate and compensate for variances of the acidity or alkalinity of body fluids through mechanisms in the brain, kidneys, lungs, and buffering system. Concept Key Terms: • Acid: any substance that has a pH less than 7.0 • Acidosis: the condition of having too much acid build up in body fluids, below 7.35 • Alkalosis: the condition of having too much alkaline build up in body fluids, above 7.45 • Anion: a negatively charge…

this experiment was to determine the percent by mass of acetic acid within a sample of vinegar using volumetric analysis with the titration technique. The theory is that if the volume and molar concentration of the standardized sodium hydroxide (NaOH) solution is known, then the percent by mass of the acetic acid (CH3COOH) in vinegar can be calculated after a titration.1 Within this experiment, a NaOH solution was standardized with a primary standard acid of potassium hydrogen phthalate…

Proximate analysis The analysis result of proximate composition of dried laver (P. species) has presented in Table 1. In our study, the crude protein of commercial dried laver was found to be (42.99 ± 0.051g/100g DW) and the moisture content was (9.40 ± 0.056 g/100g DW). The ash content was found (10.30 ± 0.033 g/100g DW). Laver, in this study, contained a very small amount of crude lipids (0.49 ± 0.04 g/100g DW). The total dietary fibre of dried laver was (31.63 ±0.032 g/100g DW). The total and…

Name: Ifeolutembi Fashina Student Number: 13335535 Lab Partner’s Name: Ifeoma Agu Demonstrator: Maria Inorganic Chemistry Experiment 3: The Identification of Unknown Samples Objectives The experiments were carried out in order to identify 15 samples, through their physical and chemical properties. Theory A precipitation reaction is one which produces an insoluble salt as product. An example would be; Ca(NO3)2 + H2SO4 = CaSO4 + 2HNO3 The calcium salt is insoluble. Precipitation reactions…

The purpose of this experiment was to learn techniques to determine the freezing point of a pure benzophenone, a solvent. Furthermore, methods for determining the freezing point depression in relation to the solute, cyclohexanone, concentration were employed in addition to learning what molality is and how it related to the colligative properties being studied. These objectives were achieved by melting both pure benzophenone and benzophenone/cyclohexanone solutions (two solutions with…

Uranium and its decay products can be found in the environment through a wide array of anthropogenic activities such as mining, nuclear and power generation industries and the production of phosphate fertilizers .(Sprynskyy et al. 2011) They pose a severe, long term ecological and public health threat (Khani 2011, Landa 2003) and therefore there is a considerable effort in the removal of these pollutants before their final discharge in the environment, as well as their recovery as an energy…

PRE FORMULATION STUDY: Pre formulation testing was an investigation of physical and chemical properties of a drug substance alone and when combined with excipients. It was the first step in the rational development of dosage forms. Class: -Pre formulation study can divide into two subclasses: API characterization, Compatibility study Active pharmaceutical ingredient (API) characterization:- Organoleptic evaluation:-These are preliminary characteristics of any substance which is useful in…

Betacyanin pigments from beta vulgaris vacuoles were use in this experiment to determine the various effects of diffusion into its surrounding environment: 60%detergent, which is shown in the figures below. The four figures below are a set of data that were collected and analyzed the effects of time, salt concentration and ionic compositions on the rate of diffusion. Both figure one and two show a set of measurements between two different salt concentrations representing their absorbance versus…
