Vitamin C tablets contain ascorbic acid (C6H8O6) and a starch filler which holds them together. Tabulate the data for the entire class. The hydrogentartrate anion itself is a weak acid and slightly dissociates in aqueous solution: Since the equilibrium constant for this dissociation is small (Ka2=7 x 10-5) we can use the assumption that the HTar- has not significantly dissociated. the concentration of K+ (aq) ions increases from the dissolved KCl. Since H and S were both positive, the dissolution of potassium hydrogen tartrate was spontaneous at high temperatures. the beaker to be weighed. The resulting precipitate was collected by filtration, washed with water, dried in a vacuum oven at 60 C. to afford 3-(4-(3-amino-6-chloropyridazin-4-yl)piperazin-1-yl)benzoic acid (0.68 g, 2.00 mmol, 100% yield) as tan solid. endobj <> Its solubility If enough KOH is Then, a small Beral pipet was filled The dissolution of potassium hydrogen tartrate in water can be represented by the equation below: KHC4H4O6 (s) - K+ (aq) + HC4H4O6- (aq) .
