Explanation Calculation of concentration of ascorbic acid solution: 5.0 m g of ascorbic acid is dissolved in one liter of water. Hence the concentration of ascorbic acid solution is given below. 5.0 m g C 6 H 8 O 6 1 m L s o l u t i o n × 1 g 1000 g × 1 m o l C 6 H 8 O 6 176 g C 6 H 8 O 6 × 1000 m L 1 L = 0.028 M . Where, the molecular mass of ascorbic acid is 176 g / m o l . Ascorbic acid is diprotic acid, so it can be represented as H 2 A . The equation for the equilibrium can be written as given below. H 2 A ( a q ) + H 2 O ( l ) ⇌ H 3 O + ( a q ) + H A − ( a q ) The acid ionization constant for the above equation can be written as given below. K a = [ H 3 O + ] [ H A − ] [ H 2 A ] According to the question. Only the first ionization is important to determine the p H . A table can be set up as given below. H 2 A ( a q ) H 3 O + ( a q ) H A − ( a q ) I n i t i a l c o n c . ( M ) 0
