Titration: Titrations are a quantitative chemical analysis technique. They are done to tell us how much acid is required to neutralise a certain quantity of alkali. A titration is a technique in which a solution of reactant (the titrant) is added to a solution of a second reactant (the analyte) until the end point is reached. The end point of the titration is the point at which the titrant has been added in the right quantity to neutralise the analyte. Usually you can see this by adding a reagent

Electrolytic Conduction Introduction Electrical conductors can be classified into two types: (1) electronic conductors and (2) electrolytic conductors. Solid and molten metals‚ semiconductors‚ and some salts are examples of electronic conductors. Conduction takes place in electronic conductors by direct migration of electrons through the conductor under the influence of an applied potential. Here the atoms or ions that compose the conductor remain stationary (except for vibrations about

Introduction: The purpose behind (the first step in) this experiment is to show that similarly to week 1‚ the molarity of an acid or base in solution can be determined (so long as one value’s is known) using titration. In this case though‚ finding the molarity of the acid used in the reaction is then used to determine the percent of that acid in a vinegar solution and compared to the standard value for % acid present in vinegar. The second part of the experiment was to see if by titrating a solution

TASK 4A Explain why it is important when producing pharmaceutical products ready for consumers to prepare standard solutions and to carry out titrations accurately in a quality control laboratory. D1 Standard solution First of all a standard solution is a solution with the accurately known concentration. The unit of concentration is mol dm–3. [4]If we didn’t have standard solutions‚ we would be calculating information which is wrong of the solutions used for pH‚ absorbance‚ etc. if we didn’t have

acetic acid in vinegar by titration with the standardized sodium hydroxide solution. Introduction: Vinegar is a dilute solution containing acetic acid. Since vinegar has a low pH‚ it can be titrated with a base. Titration is a method used in order to ascertain the amount of a constituent in a solution by measuring the volume of a known concentration of a reagent required to complete a reaction with it‚ typically using a burette. The equivalence point of a titration occurs when chemically equivalent

Determination of Vitamin C Concentration by Titration (Redox Titration Using Iodate Solution) Introduction This method determines the vitamin C concentration in a solution by a redox titration with potassium iodate in the presence of potassium iodide. Vitamin C‚ more properly called ascorbic acid‚ is an essential antioxidant needed by the human body (see additional notes). When iodate ions (IO3−) are added to an acidic solution containing iodide ions (I−)‚ an oxidation-reduction reaction occurs;

Samples were taken at the end of each space time and by using back titration method how much NaOH remained unreacted was determined. This was continued until steady state is reached for each space time. In back titration‚ 10 mL of HCl is

The Titration of a Basic Solution of Unknown Molarity with a Standard Hydrochloric Acid Solution Abstract The aim of the experiment was how to determine the molarity of a solution. My hypothesis was if I have to determine the molarity of a NaOH solution‚ then I would have to use a standard solution of HCl solution because I would need to neutralize each other to determine the concentration of the solution of NaOH. The method that I used for this experiment was titration. Titration helped
