It is important to perform more than one titration because you will never be precise when performing the titration lab. Therefore, performing more than one titration and taking the average of the trials will give the most precise observations.3) It is important to rinse all glassware with the solution type that will eventually be placed in it to remove ions or impurities in the flask which may react with the solution that are poured into it. Once the burette is rinse with the solution to remove the water, the concentration of the solution is not lowered which will not affect the accuracy of the results.4)If the same indicator was used for a base titration, the colour change would be the opposite of what truly occurred in the lab.

Determination of Cu2+ by Titration

658 words - 3 pages Determination of Cu2+ by Titration Introduction: The purpose of this lab is to determine the concentration of copper ions in an unknown solution. Complexometric titration will be used to determine the concentration. A buret will be used to deliver the complexing agent to the unknown solution. Ethylenediaminetetraacetic acid will be used as the complexing reagent. An indicator, Murexide in our case, will be used to indicate the endpoint of

Chemistry: What is A Complexometric Titration

3189 words - 13 pages Introduction: According to (Khan): A complexometric titration as defined by IUPAC as a volumetric titration where a soluble complex can be formed by titrating a metal ion with a ligand in an aqueous solution and a titrant is one of the reacts used in the titration. [4] M(H2O)n + L = M(H2O)(n-1)L + H20 [4] (Khan): further states, here L are the Ligand and which is formed via the complete replacement of water molecules by other ligands can occur

1532 words - 6 pages AbstractBy using acid-base titration, we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein's color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric

Titration with unknown concentration of Hydrochloric acid - Research Paper

1277 words - 6 pages indicator is introduced the molecules attach to the H+ resulting in an abundance of single bonds absorbing the same wavelength and producing a defined colour. However, when introduced into an alkali solution the distinct lack of H+ ions result in the more double bonds forming, changing the wavelength of light that is absorbed so that the solution appears another colour. Used in analytical chemistry, the method of titration is employed to

The KHP solution will be poured in a flask along with a few drops of one of three indicators we will be evaluating. The NaOH solution will be poured into a buret (with volume markers) and will be used as the titrant. The strong base will be added slowly to the acidic solution, gradually neutralizing the acid. The

Complexometric Titration Essay

2854 words - 11 pages Complexometric titration is defined as a form of volumetric analysis in which the formation of a coloured complex is used to indicate the endpoint of the titration (1). Complexometric titrations rely on the formation of complexes between metal ions and compounds capable of donating electrons to form a stable, soluble complex (2). The complex is formed as a result of metal ions being titrated with a complexing agent or ligand. The principle of
