- Think that an alloy Cu-60wt%Ag is slowly cooled from the Liquid Phase Field. How many grams of total alpha are present at 778°C? The total alloy amount is 1000gramsA solution of sodium thiosulfate, Na2S2O3 was standardized by dissolving 0.188 g of KIO3 (MM = 214.00) in water, adding a large excess of KI, and acidifying with HCl. The liberated iodine required 18.25 mL of the thiosulfate solution to decolorize the blue starch/iodine complex. Calculate the molarity of Na2S2O3 solution. Stoichiometry of the reaction is: 1 mol IO3- = 3 mol I2 = 6 mol S2O32-The magnetic moment of [Mn(NCS)6]4- is 6.06 μBM, is it high or low spin? why?
