28 > The active ingredient in a zinc nutritional supplement is ZnSO, 7H, (molar mass=287.58 g/mol). Ten zinc tablets containing a mix of the active ingredient and an inactive filler were ground and mixed together thoroughly. The total mass of these 10 tablets was 11.285 g. A 2.056 g sample of the finely ground tablets was dissolved in an acidic solution. The solution was neutralized with ammonia and subsequently warmed in a water bath. Addition of (NH), PO, to the...

SO) groups so that if the Na salt is prepared it will be soluble in water. One synthesis of indigo carmine involves heating the precursor dione with sulfuric acid. Draw a complete curved arrow mechanism for electrophilic substitution of one of the aromatic rings (you may abbreviate the dione structure). This mechanism needs to include formation of the reactive electrophile from sulfuric acid. Draw one resonance structure for the carbonyl group and a second resonance structure for the amine group...
