Claudia determines the concentration of sodium hypochlorite, NaOCl, in bleach using a redox titration that requires two steps. First, she acidifies the NaOCl and adds excess iodide to produce iodine. Next, she titrates the iodine using a solution of standardized sodium thiosulfate, Na2S2O3. Claudia observes the end point of the titration after adding 0.751 mL of 0.150 M Na2S2O3 to 0.081 g of a commercial bleach product. Calculate the percent by weight of NaOCl in the bleach sample.

Asa choose the correct set of reaction coefficients to properly balance the following chemical equation according to the law of conservation of mass: __s8 + __o2 ==> __so2 1, 1, 8 1, 8, 1 1, 8, 8 8, 1, 1

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
