The actual pII of the substance is 7.3, but due to errors any time the chemist performs the titration, the pII she observes will be normally distributed with a mean of 7.3 and a standard deviation of 0.5. In order to minimize the possibility of ...

WebQuestion: The quantity of antimony in a sample can be determined by an oxidation–reduction titration with an oxidizing agent. A 7.21 g7.21 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCl(aq)HCl(aq) and passed over a reducing agent so that all the antimony is in the form Sb3+(aq).Sb3+(aq). WebAcid-base Titration. Objectives: To determine the percentage by mass of calcium carbonate in an egg shell . Results: The first product is composed by the reactants: 0.6 grams of a ¨impure¨ sample of calcium carbonate and 20cm 3 of 1.00 mol/dm 3 hydrochloric acid solution, and it forms the following equation: .
