6. (15 pts) You have a sample that is a mixture of Na.Co, solid with NaCl solid. You dissolve 4.000 grams of the mixture into enough water to make 50.00 mL of solution. You find that when you titrate your unknown solution, you require 42.19 mL of 1.000 M HCl for complete neutralization. What percentage (by mass) of the unknown mixture is Na CO,? Titration reaction: Na.Co. (aq) + 2 HCl(aq) → 2 NaCl(aq) + C048)...

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...
