of chlorine ions Aim: To compare the concentration of chloride ions in pool and tap water respectively. Background: Tap water contains a variety of dissolved ions such as Ca2+‚ Mg2+‚ Na+‚ HCO3- and Cl-. In this experiment we will determine the concentration of the Cl- ions‚ and comparing it to the concentration found in a sample of pool water. The method used is the standard one for determining the concentration of chloride ions: titration with silver nitrate solution of known concentration

Title : Osmosis in Quail’s Eggs Research Question What is the effect of different concentrations of sodium Chloride (NaCl) on the mass of the de-shelled quail’s eggs? Introduction Osmosis is an example of passive transport. Osmosis is defined as the movement of water molecules‚ down its concentration gradient‚ from an area of high water concentration (low solute concentration) to an area of lower water concentration (high solute concentration) through a selectively permeable membrane. Osmosis

Title: Osmosis in quails’ egg Aim: To observe the effect of different concentrations of sodium chloride on a de-shelled quail’s egg To explain the effects in terms of osmosis Research Questions: Does the different concentrations of sodium chloride on a de-shelled quail’s egg effect the final mass of quail’s eggs that is measured by using electronic weighing balance? Introduction: “If a cell is to perform its functions‚ it must maintain a steady state in the midst of an ever-changing

varies between 5 and 100 ptb. Chlorides Crude oil brine analysis varies‚ with 75 percent sodium chloride‚ 15 percent magnesium chloride‚ and 10 percent calcium chloride considered average. Chloride salts are the source of hydrogen chloride that is evolved during distillation. Magnesium chloride is the most prolific producer of HCI with calcium chloride and sodium chloride ranking second and third‚ respectively‚ in HCl production. As the concentration of a chloride decreases‚ the evolution rate

Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction

Title: Determination of chloride by the Mohr Method Objective: To determine chloride by using Mohr Method. Introduction: The Mohr method is the method used to determine the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added‚ a precipitate of silver chloride forms. Ag+ + Cl- AgCl(s) (Ksp for AgCl is 1.810-10) The chloride ion (Cl-) is an important anion found in solids and solutions. Chloride is the predominant anion
