Precipitation Titration Mohr Method Experimental The chloride ion (Cl-) is an important anion found in solids and solutions. In this experiment‚ the amount of chloride ion in an unknown sample J (NaCl + KCl mixture) of water using the Mohr method is determined‚ which relies on the solubility differences of two anions and the titration endpoint of a precipitate. The net ionic reaction during the titration is as follows: Ag+ + Cl- → AgCl(s) The Ksp for AgCl is 1.8 x 10-10 and

Titration is a method used to help determine the concentration of an unknown solution (the analyte) by using a solution of known concentration (the titrant).1 In medicine‚ titration helps doctors determine unknown concentrations of substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately
Premium Chemistry Sodium hydroxide Titration
Titration Lab of NaOH and KHP Aim: To titrate Sodium Hydroxide with Potassium Hydrogen Phthalate . To also determine the concentration of NaOH in the KHP solution. Hypothesis: When KHP is added to the solution of NaOH and the indicator‚ the solution will turn clear and neutralize. The concentration of NaOH is going to be very low because it is diluted. Materials required: pipette filler‚ volumetric flasks(2-4)‚ beakers(2)‚small white piece of paper‚ indicator( 2 drops)‚ conical flask‚ clamp

Aim: To calculate the concentration of acid in a sulphuric acid solution. Introduction: A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and the precise quantity of reactant in the titration flask. A burette is used to deliver the second reactant to the flask and an indicator is used to detect the endpoint of the reaction. So a chemical reaction is set up between a known volume of a solution of unknown concentration and a known volume of

added the solution will quickly start to turn yellow due to formation of MnO2. If this happens anyway‚ add some more sulphuric acid to reverse the process. The solution should be clear with a slight green tinge. Chapter 15 – Volumetric analysis (Redox titrations) To prepare a standard solution of ammonium iron sulphate and use this solution to standardise a solution of potassium permanganate. Potassium permanganate (KMnO 4 ) is a powerful oxidizing agent and is a deep purple colour. It cannot be

Acid-Base Titration and Volumetric Analysis The purpose of this experiment is to determine the [NaOH] of a solution by titrating it with standard HCl solution‚ to neutralize a known mass of an unknown acid using the NaOH solution as a standard‚ to determine the moles of NaOH required to neutralize the unknown acid‚ and to calculate the molecular mass of the unknown acid. Procedure: Part A: Standarized 0.10M HCl solution and unknown NaOH solution were poured into two beakers. The burets

a chelating ligand. The base‚ EDTA‚ will bind to the metal ions‚ which serve as the Lewis acid‚ thus playing a role as a ligand. The indicators used in EDTA titrations are metal ion indicators. Metal ion indicators work by the presence of absence of metal ions. Just like EDTA‚ the metal ion indicators will bind with metals. When the titrations begin‚ Mg2+ will be formed in a complex with the indicator. Once EDTA is added‚ it binds to the free Mg2+ ions‚ and then it reacts with the Mg2+ ions that

Acid-base titration Aim To study the titration curve of a strong base-strong acid‚ strong base-weak acid and weak acid-strong base titrations Introduction Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. When an acid and a base are present in a stoichiometric amount e.g. 1 mole HCl added to 1 mole NaOH‚ this means that the equivalent point has been reached in an acid-base system. The end point of an acid-base titration can be detected
