You wish to determine the %concentration of a stock solution of brilliant blue FCF
(MW=792.8grams/mole; extinction coefficient,25=97000M1cm 1).
You take 5ul of the stock and dilute up to 1ml. You take 10ul of this dilution an dilute it up to 500ul.
Finally you take 1ul from this dilution and dilute it up to 1ml in a 1cm diameter cuvette.
You obtain an As91=0.001 SHOW YOUR WORK. Do not forget units.

A solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2. A. Can the metal ions be separated by slowly adding Na2CO3 aq solution? Assume that for successful separation 99% of the metal ion must be precipitated before the other metal ion begins to precipitate, and assume no volume change on addition of Na2CO3 solution. Ksp of CuCO3 = 1.4 x10-10 Ksp of NiCO3 = 1.42X 10-7 B. If you need to redissolve the salt that was first precipitated, what pH will you use and why ? Write your answers in template provided.
