Suppose you have a solution that contains 0.0470 M Ca2 and 0.0910 M Ag . If solid Na3PO4 is added to this mixture, which of the following phosphate species would precipitate out of solution first? Ca3(PO4)2 is the answer to part 1. When the second cation just starts to precipitate, what percentage of the first cation remains in solution?

10.0 g of alloy containing only Fe, Cr and Ni when heated with dil. HNO3 dissolved to give Fe3+, Cr3+ and Ni2+ respectively. The resulting solution was diluted to a total volume of 250.00 cm3 by adding distilled water. 25.00cm3 of the diluted solution was treated with excess NaOH and H2 O2 . The obtained precipitate P was fltered and yellow colour fltrate Q was acidifed with dil. H2 SO4 acid, and titrated with 1.0mol dm-3 Fe2+ solution. The volume...

Q 1 & 2
1. Sodium ion (Na) and calcium ion (Ca2) produce nearly the same color in a flame test (yellow and yellow-orange, respectively). Describe a way to differentiate between the two using a solution of Na,CO and write the correct balanced equation(s). (Hint: recall the solubility rules for Na ion.) A saturated solution of an unknown solid reacted with AgNO, to give a pale yellow precipitate, and also reacted with Pb(NO), to give a white precipitate. Based on...
