For each numbered step in the qualitative analysis scheme in number 5 above, type all net ionic equations associated with the step. Write only the final net ionic equations for the general qualitative separation scheme above. Refer to Experiment 7. You were asked to do this there as well. 7. A summary statement providing your logic, with reference to experimental observations, for choosing the ions in your unknown.

Answer 1

Mt Mt Hee Mer & MC (Agce(s), PbCl (s) and Hg, C, (o) are separated) For Cat Nat M + Whey, Batik (NH4)₂SO4 I msoq et M₂ 504 - Only BasOy is separated Fox Caht Myt Nat, k me what | (NHa) CZ04 Ca ( 4 ) t only cast is separated. and residue) fitrate.

Agcet Phle & Hg, Cl₂ heat soluble (tiltrate) Phel2: cro and residue) асі, ға, а, NH₂ y sa Hiltuate * Pb (Croat Yellow ppt) Hoch (soluble) (résidue) [Ag (NH), Ti. 7) As solubility product of Age, a P bel and Hp Cl is very small, they are easily precipitated. Basly is almost insoluble in water, it is separated tipbal, is insoluble in cold water but soluble in hot water. Only co2t reacts with or to form Ca(Og) - that is insoluble I say met can't be recognized by flame test.
