Pure Copper Iodide were synthesised and the mass percentage of Copper in purified Copper (I) Iodide sample were determined by applying Beer’s Law in UV-Vis spectroscopy. Absorbance value of Cu-cuprizone solution was measured. Using the absorbance value of 0.3576 , the concentration of the Cu-cuprizone solution were obtained at 0.001389g/L with reference to the graph of the standard solution A to D. The graph of absorbance against concentration of the standard solution A to D shows a linear…

2.1. C. tomentosum extract characterization C. tomentosum extract proximal composition is shown in Table 1. The relatively higher ash proportion in seaweed extract (SE) (aprox. 74%) could largely be accounted for by the lower moisture content, and probably due to a hygroscopic nature of the SE (Blanco-Pascual, Montero, & Gómez-Guillén, 2014). The values of TPC and DPPH radical-scavenging activity are consistent with literature (Andrade et al., 2013; Valentão et al., 2010) (Table 1). POD and PPO…

release tablet. UV spectrophotometric method was developed and validated to study drug release profile of Ketorolac Tromethamine and Phenylephrine Hydrochloride in immediate release tablet. Background: Ketorolac Tromethamine is a pyrrolizine carboxylic acid derivative structurally related to indomethacin. It is an anti inflammatory drug with analgesic and anti pyretic effect. Phenylephrine Hydrochloride is a sympathomimetic amine that acts predominantly…

Hopkins University. 2.2.2 SYNTHESIS OF SILICA GEL 2.2.2. a) USING KAOLIN BY-PRODUCT The synthesis process (D. Brahmia 2014) was carried out in two steps namely, (1)Metasilicate sol preparation and (2) Metasilicate destabilization with acid. In the first step, a mixture of sodium carbonate and sand were heated to 1000°C to form silicate. Sodium silicate formed in this study was prepared with different molar ratios, n, ranging from 1 to 4 as shown in Equation (2.1). The result…

Based on our experimental results, we can conclude that our hypothesis is correct (Graph 2). To further explain, there is a greater amount of the enzyme available for the dopa to interact with and will lead to more formation of dopachrome. The rate of the enzyme-catalyzed as measured by velocity, also showed a linear relationship (Graph 3) and the enzyme being a limiting reactant, so the reaction will proceed at a maximum velocity. When the substrate…

Pink Lips Naturally: Carrot and Beetroot Juice: The pink lips are carrot and beetroot juice. Carrot contains cancer prevention agent which helps in helping the skin. Peel the carrot skin and smash the carrot in the blender processor and take the carrot juice. Presently apply the carrot squeeze in the lips at whatever point you have time. Utilize this consistently for better outcomes. Beetroot likewise contains cell reinforcement so it additionally turns dark lips to blushing sparkly lips.…

Abstract: A one dimensional variable range hopping type conduction is observed in Poly (3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT : PSS) films and the mechanism behind enhancement in conductivity in 3% dimethyle sulfoxide (DMSO) doped PEDOT:PSS film is due to the phase segregation of PSS on the surface and reduction of energy barrier between the conducting grains. Enhanced conductivity of PEDOT:PSS films and transparency more than 80% in the visible region makes PEDOT:PSS films…

Currently, Lagoa Vermelha has a depth of 1.0 m, with a small central core reaching a depth of 1.4 m, while Hohn et al. (1986) described a water column up to 1.70 m. In the present study, there was a greater tendency of accumulation of fine material, with little concentration of carbonates, at the highest depths. As expected, the accumulation of fine sediment was also associated with higher concentrations of organic matter. The results obtained in the bathymetric survey showed occurrence of a…

aids in digestion and helps to relieve digestive problems as well. • Stimulates hair growth: Mustard oil contains high levels of beta carotene and Vitamin A, iron, fatty acids, calcium and magnesium that stimulate the growth of hair and keep it healthy. • Improves heart health: Mustard oil is rich in omega-3 and omega-6 fatty acids which lower the cholesterol levels and promote the good cholesterol which in turn ensure that the cardiovascular health is maintained. Consuming mustard oil helps to…

Noor Diabi 11AA The life of hydrochloric acid in our stomach Chapter 14 section 1 25/04/2016 Ms. Sara Kassem Sharjah American International School Topic one: Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produced.  Hydrochloric acid (HCl) is a clear, liquid. Which is produced in…
