In the United States, table salt is “iodized” and contains NaCl and a small amount of KI. The iodide was added to help prevent thyroid disorders in the population. The iodide concentration in table salt was measured using the following steps: 1.000 g of table salt was dissolved in 100.0 mL of water. The salt solution was titrated using 4.00 × 10−5 M Ag+ and a Volhard titration (back titration). 15.00 mL of 4.00 × 10−5 M Ag+ solution was...
A 0.3146 g sample of a mixture of NaCl(s) and KBr(s) was dissolved in water. The resulting solution required 51.40 mL of 0.08765 M AgNO3(aq) to precipitate the Cl−(aq) and Br−(aq) as AgCl(s) and AgBr(s). Calculate the mass percentage of NaCl(s) in the mixture.
A 0.3146-g sample of a mixture of NaCl(s) and KBr(s) was dissolved in water. The resulting solution required 48.80 mL of 0.08765 M AgNO3(aq) to precipitate the Cl–(aq) and Br–(aq) as AgCl(s) and AgBr(s). Calculate the mass percentage of NaCl(s) in the mixture. ______% NaCl
6. A 1.500 g sample of a mixture of solid Na PO, 12H.O mixed with NaCl, was dissolved in water, reacted with aqueous 1 M SrCl, and 0.520 g Sr.(PO), precipitate was collected and dried to a constant mass. If the reagent tests demonstrated that Na PO:12H.O was the limiting reactant in the precipitation reaction, calculate the mass percent of Na PO, 12H 0 in the original sample. a. How many moles of Sr,(PO), were produced? b. What is the...
