  • Titration In Gastric Acid Essay

    Determination of the Concentration of Acid in Gastric Juice Introduction Titration is a method where a solution of known concentration is used to find the concentration of an unknown solution. A standard solution is a solution of precisely known concentration. The aim of this experiment was to go over the use of pipettes, burettes, titrations and also to reinforce the concept of molarity. In this experiment, a titration was carried out using a standard solution of hydrochloric acid to establish the molarity of a solution of sodium hydroxide. The concentration of acid in the gastric juice sample was determined using that solution of sodium hydroxide. The pH of gastric juice was then calculated and compared with the value determined by…

  • Simulated Gastric Chloride Acid

    Dissolution test will be carried out in a simulated gastric fluid (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…

  • Gastric Acid Secretion Research Paper

    proper everyday functions. A large process in this region of the body is gastric acid secretion. This secretion occurs from a number of different mechanisms. However, this process is largely contrived through two means, parietal cells and drugs. Utilized each day in processes like digestion and metabolism, the role parietal cells and drugs play in regulating gastric acid secretion is fundamental to life. Gastric Acid Secretion by Parietal Cells Gastric acid aids digestion by creating the…

  • Factors Related To The Oral Cavity That May Impede The Process Of Digestion Of Food

    individual sections of the digestive tract. The highly acidic pH of the stomach’s gastric juice is needed to not only prevent bacterial growth, but to create an optimal environment for it’s enzymes to digest the food (now chyme) received through the cardioesophageal sphincter. The small intestine cannot handle such high pH, therefore when the stomach releases chyme into the small intestines, a signal is sent to the pancreas to release an alkaline substance called “sodium bicarbonate” to…

    oesophageal sphincter (LES) and into the stomach. The digestive juices secreted by the stomach are highly acidic. When the stomach contracts to move the food into the intestine the LES closes tightly in order to prevent these acidic juices from moving back into the oesophagus where they can cause damage. The diaphragm separates the chest from the abdomen, to reach the stomach the oesophagus passes through the diaphragm at a point called the hiatal ring. If the patient has reflux disease their…

  • Propranolol Drug Release Study

    RESULTS AND DISCUSSION The drug release study of Propranolol from the synthesized prodrugs9a and 9c proved that they hydrolyze significantly at pH 6.8 & 7.4. This proves the stability of prodrug at gastric pH and easily gets hydrolyzed at both blood and intestinal pH, and would be available for the action by significantly eliminating the problem of fast metabolism and local irritation when compared to the parent drug. The % CDR of 9c at pH 7.4 was found to be maximum i.e. 92% within 3 hrs and…

  • Acid-Base Case Studies

    Acid-Base Case study 1 The acid base balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide…

  • Acid-Base Reaction Lab Report

    The experiment performed provided insight on the importance of acid-base interactions and the pH of solutions that are involved in a variety of aspects including industrial, environmental, and biological contexts. Back titration was used to determine the number of moles of HCl acid that were neutralized by a single tablet of several variations of commercial antacids. In theory, the antacid that neutralized the largest number of moles of acid was found to be the most effective. The results…

  • Indigestion Lab Report

    INTRODUCTION: Indigestion is difficulty digesting food; it causes pain or discomfort in the stomach. Most commonly, people suffer from indigestion by overeating, drinking alcohol while eating, or eating greasy, fried or spicy foods. Acid in the stomach helps digest food and prevents infection. Mucus lines the stomach, bowel and oesophagus and acts as a barrier against the acid. If the layer of mucous gets damaged, the stomach acid can aggravate and cause inflammation to the stomach; this leads…

  • Antacid Lab Report

    substance is or if a substance is neutralized. Antacids have the ability to give relief for heartburn, indigestion or symptoms of acid reflux. There are many types of antacids such as calcium, aluminum and magnesium. They’re many ways to consume antacids such as liquids, tablets and chewable tablets. The experiment will be tested with three different antacids which are: bismuth ($5.99) (picture 1&4), life brand milk of magnesia ($8.99) (picture 2&3) and Gaviscon ($11.99) (picture 5). Purpose The…
