Ascorbic acid is an essential nutrient in many primates, including humans. A deficiency in this naturally occuring organic compound can result in a condition called scurvy, which left untreated, can be lethal. In a titration experiment to the first equivalance point, a student used a 0.500 mol/L solution of sodium hydroxide to determine the concentration of a solution of ascorbic acid. The data of this exothermic reaction were obtained: Titration of ascorbic acid with sodium hydroxide solutions. The thermochemical equation for one step of the reaction is... Select one: a. H2C6H6O6(oq)+OH(aq)HC6H6O6(aq) +H2O(05.6kJ b. H2C6H6O6(oq)+OH(oq)HC6H6O6(oq)+H2O(0) H=+5.6kJ/mol d. H2C6H6O6(oq)+OH(aq)HC6H6O6(oq)+H2O(0)+5.6kJ
