Product description
1. Sodium carbonate anhydrous - Na2CO3, reagent, chemically pure, with the content of the main component 99.96%, standardization of solutions of strong acids used as titrants in acidimetry. Calculate the molar concentration of Na2Co3 in the standard solution obtained by dissolving 0.5498 g of anhydrous sodium carbonate reagent, reagent grade, in a volumetric flask with a luminosity (500 cm3)3. What are T(Na2CO3) and C3(Na2Co3) of this solution, given that Na2CO3 is involved in a chemical reaction where f(Na2CO3) = 1/2?
