Antacids are defined as a substance‚ generally a base‚ which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux‚ gastritis‚ upset stomach and heartburn. Hydrochloric acid is secreted by the stomach to kill harmful organisms‚ aid digestion and activate digestive enzymes. Excess secretion of acid into stomach or impaired resistance by the lining of the stomach or reflux into the oesophagus may produce symptoms

example: Chemistry Laboratory Report (Magnesium Oxide) INTRODUCTION: As we learned before on how to determine the empirical formula of a compound based on the test and also chemical analysis on it. Hence this experiment is mainly goes around with how to determine the empirical formula of Magnesium Oxide following various tight procedures in order to get the knowledge and apply it onto another compounds. We are investigating the empirical formula of Magnesium Oxide in this experiment. RESEARCH QUESTION:

The element‚ magnesium is unlike most because of the way it is composed‚ and many do not know what Magnesium is. The element has unique physical properties‚ a rich history that stretches back to the 17th century‚ and lots of sophisticated uses that are used in your everyday life‚ and vital to your health as a human. Magnesium’s properties are‚ in a way‚ very unique. On the periodic table Magnesium is found in the Alkaline Earth metal group. The structure of the atom consists of twelve protons‚

The purpose of the experiment was to perform an electrophilic addition reaction by the bromination of cinnamic acid. The product of this reaction is 3-Phenyl-2‚3-dibromo propionic acid‚ which is purified by recrystallization. Cinnamic acid (3-phenylprop-2-enoic acid) is an unsaturated carboxylic acid. The electron rich π cloud (see Figure 1) in the double bond of this structure is nucleophilic and can be considered a Lewis base. It can therefore be saturated by the addition of a halogen to the double

LAB 6. ACIDS AND BASES: PH AND BUFFERS PURPOSE: To determine the pH of common acids and bases using a pH meter‚ pH paper‚ and red cabbage indicator. To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic

For this experiment me and my lab partner didn’t finish the experiment. We only end up to adding the magnesium sulfate. We added so much magnesium sulfate‚ and ended up drying the whole product without any liquid left. We were trying to do the procedure all over again but‚ we will ended up to not finishing the experiment still due to time constrain. I will try to explain the possibility what will happen up to the end of the experiment. After measuring the 10ml graduated cylinder‚ which is 27.27g

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the experiment: In this reaction two substances

great and tragic mistake. They should have been promoting magnesium. Magnesium deficiency leads to an increase in myocardial levels of both sodium and calcium. This is a problem because Coronary Artery calcium is a predictor of near-term coronary heart disease events. In the face of growing magnesium deficiencies calcium becomes increasingly more toxic to human physiology. It is magnesium that actually controls bone density not calcium. Magnesium drives the calcium into the bones where low levels encourage
