Ascorbic acid (molecular weight 176.12) is too acidic to administer by the parenteral route. The acidity of ascorbic acid is partially neutralized by adding a basic compound, usually sodium carbonate or sodium bicarbonate. Thus, the injectable produc contains sodium ascorbate, ascorbic acid, and the neutralizing agent. (a) Whatis the pHof an injectable solution containing only ascorbic acid in the concentration of 55 g per liter of solution? K, = 5 x 10-3 and K2= 1.6 x 10-12
