The Ka1 of ascorbic acid is 7.94 x 10°. Would you expect ascorbic acid dissolved in blood plasma (pH 7.35-7.45) to exist primarily as ascorbic acid or as ascorbate anion? From the choices provided below, indicate whether the carboxylic acid will exist primarily in its protonated form as a Free Acid or in its deprotonated form as a Carboxylate Anion by clicking on the corresponding button. At equilibrium in this pH, the concentration of the preferred form of the acid is approximately times higher than the concentration of its conjugate form. Round to the nearest order of magnitude.
