    (SGF) using hydrochloride acid or a neutral buffer phosphate solution. The simulated gastric fluid without enzyme (SGF) at pH 1.2 and pH 3 containing sodium chloride and hydrochloric acid in 900ml deionized water will be prepared. Thus, the pH will be adjusted using hydrochloride(Ghazal et al., 2015). The simulated gastric media containing milk (whole milk, skimmed milk) will be prepared using an equal volume of milk and (SGF) pH 1.2(Ghazal et al., 2015). Amino acids lysine, glycine and…

    • 5 Pages

    1.1 Introduction/ what is Acid Rain? Acid rain, or acid precipitation is a term used to describe any form of precipitation with a pH of less than 5.6. In recent years, the effects of acid rain are being experienced on a global scale with widespread environmental effects. Primarily, acid rain is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from the combustion of fossil fuels. However, even pure rainwater is slightly acidic (pH of 5.6-6.5) due to the reaction between H2O…

    ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…

    Kinetic investigation and the Arrhenius plot The degradation of SAC in acidic, basic and oxidative mediums at different HCl (0.01, 0.05 and 0.1 M, keeping temperature 90 ºC), NaOH (0.005, 0.01 and 0.05 M, keeping temperature 40 ºC) and H2O2 (5%, 10% and 15%, keeping temperature 90 ºC) strengths was studied. Also SAC degradation was studied as a function of temperature in acidic (30, 60, 70, 90ºC and room temperature, keeping HCl strength 0.1M), basic (40, 65, 90ºC and room temperature, keeping…

    Acid and Base Theories Final Paper In the world of science, there are three main theories for acids and bases. Those three theories are the Arrhenius theory, the Bronsted-Lowry theory, and the Lewis theory. An Arrhenius acid is defined as a substance that increases the concentration of hydronium ions in aqueous solution and an Arrhenius base is defined as a substance that increases the concentration of hydroxide ions in aqueous solutions. The definition of a Bronsted-Lowry acid is that it is a…

    magazine Nature that bacterial growth and overall metabolism can be inhibited by alterations in the pH of the culture. The active ingredient hypochlorous acid, found in bleach, affects proteins in bacteria by changing the pH of the environment and therefore denaturing them by affecting their secondary and tertiary structures. Moreover, hypochlorous acid has been found to have the same…

    resources daily to survive. One big problem effecting natural resources and the environment is acid rain. Acid Rain is precipitation with high levels of acidic components. Precipitation can be in the form of rain, snow, sleet, fog, or dust. There are many different causes and effects of acid rain. Humans are trying to find a solution, and the Federal Government has enacted many laws to help prevent acid rain. Rain is naturally acidic, but pollution is increasing rains’ acidic value. Pollution…

    can we differentiate acids and bases? How do we know if a substance is an acid or a base? There are different methods to discover whether a substance is an acid or a base. One of the methods is by using an acid-base indicator or by identifying hydrogen or hydroxide ions in a substance’s chemical formula. Certain materials such as a plastic template, red litmus paper, blue litmus paper, phenolphthalein, universal indicator, and a pH chart can be used to help us distinguish acids and bases.…

    INTRODUCTION 1.1What is an acid-base titration? An acid –base titration is the determination of the concentration of an acid or base by neutralizing the acid or base with an acid or base of known concentration. An acid-base titration is the analysis of the concentration of acids and bases; through this process an acid or base of known concentration neutralizes an acid or base of unknown concentration. The neutralization of an acid or base in acid-base titration can be measured with either a…
