Determination of the Concentration of Acid in Gastric Juice

Introduction A titration was carried out in this experiment to honour the closeness of hydrochloric acid is an unknow origin. The aim of this experiment is to specify the regulation of moles of sodium hydrated oxide in hydrochloric acid and wherefore to posit the number of moles of sodium hydroxide present in stomachic juices. Titration, or meretriciousnesstric analysis, is a common laboratory capital punishment for the analysis of substances and results. In a titration, the analyst determines the volume of a root, called a titrant, that counterbalances exactly with a cognize weight or volume of another substance. This fight backion is carried out by adding a solution of reactant hydrochloric acid from a burette to a solution of sodium hydroxide until just sufficient of hydrochloric acid has been added to react with all of the sodium hydroxide. If the concentration and volume of hydrochloric acid is cognize the number of moles of sodium hydroxide pot be calculated, if the par for the reaction is known. This procedure is known as a titration and the point at which sufficient volume of hydrochloric acid has been added to the sodium hydroxide to complete the reaction is called the revoke point. An indicator which changes colour at the equivalence point is often used to indicate the titration quit point.

This stepized solution of sodium hydroxide can then be used to determine the concentration of acid in the example of gastric juice. Acid- fundament titration is when a titration is carried out with a known volume of a watertight acid which in this episod e is HCl, of unbeknown(predicate) concentra! tion, with a standard solution of a strong base NaOH. The reaction taking place is: HCl(aq) + NaOH(aq) ? NaCl(aq) + H2O(aq) A titration can be used to find the concentration of an acid in gastric juices because the acidity in the gastric juices is mainly caused by hydrochloric acid. Therefore, by doing the simple acid base titration with a standard solution of hydrochloric...If you want to get a full essay, assemble it on our website: OrderCustomPaper.com
