hydrochloric acids (HCl) and indigestion relief tablet. I will also mention the time which was taken in the experiment‚ to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. Indigestion Tablet Indigestion is caused by excess acid in the stomach. The tablets neutralise some of this Acid and this is known as ‘Neutralization’ since it neutralizes the acid. In this

Experiment on Metals Aim-To find out which of these metals will be most reactive with hydrochloric acid‚and plan an investigation to test it out.The Metals given:Calcium‚Aluminium‚Iron‚Magnesium and Zinc. Prediction-I predict that the metal will be the most reactive with hydrocholoric acid is calcium because calcium is in Group 2 which is the alkaline earth metals in the periodic table and because calcium is at the extreme left side of the periodic table and as you go across a period‚the element

Acid Rain: The Southern Company (A) Problem Statement In 1992‚ executives at the Southern Company have three years to formulate a robust and complex strategy that will involve massive capital outlay and substantial modifications to processes and procedures as it works to comply with provisions enacted in 1990 to the amendments of the Clean Air Act‚ while simultaneously ensuring they remain sustainable and profitable. Analysis The Southern Company is an American based electric utilities

Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g

Acid Rain: The Southern Company (A) Case Study #1 2/01/2012 Situation: The acid rain provisions of the 1990 amendments to the Clean Air Act were to being in 1995. Currently‚ it is 1992 and The Southern Company (a electric utilities holding company operating in Georgia‚ Alabama‚ Mississippi‚ and Florida) had to decide what actions they were going to take in order to comply with the new regulations. Before the Clean Air Act‚ firms did not have incentives to reduce emissions below the government

But-2-enedioic acid Introduction Cis-trans isomers are a kind of stereoisomers called geometrical isomers. Due to the inability of rotation about the C=C bond‚ some compounds possess cis and trans isomers. But-2-enedioic acid is an example of having both isomers. Maleic acid Fumaric acid Cis and trans isomers have different physical properties such as boiling point‚ solubility‚ density and stability. In this experiment some maleic acid is converted to fumaric acid by

The Central Role of the Citric Acid Cycle 3 processes play central roles in aerobic metabolism. The citric acid cycle. Electron transport . Oxidative phosphorylation. Metabolism consists of: Catabolism: the oxidative breakdown of nutrients. Anabolism: the reductive synthesis of biomolecules. • The citric acid cycle is amphibolic

The identification of acids and bases using a natural indicator Purpose: The purpose of this lab practice is to identify the pH of certain solutions and if they are acids or bases. Introduction: In chemistry‚ pH is a measure of the activity of the (solvated) hydrogen ion. p[H]‚ which measures the hydrogen ion concentration‚ is closely related to‚ and is often written as‚ pH. Depending on the pH solutions will be acids or bases. An acid is a chemical compound that dissociates in solution‚ releasing

Acid-Base extraction theory states that when an acid reacts with an organic base it results in a salt that is water-soluble and a neutral molecule that is insoluble. The addition of an acid to a mixture containing acids and bases will result in the acid remaining unchanged and the base reacting to form a salt. The results from the experiment were fairly consistent when separating the strong acid‚ weak acid‚ or the base. In part one of the experiment‚ you had to separate the strong acid. When added
