- 2. a. What ingredient(s) necessary to white chocolate does this product have? b. Why is this product labeled as “white chocolate style” instead of being simply labeled as “White chocolate”?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. Upload your step by step solution for A.The iodine contained in every one mL of the 0.010 M iodine solution in the buret will react with 1.76 mg of vitamin C.
