From the diagrams given in the problem statement, The diagram representing a solution of a weak diprotic acid has to be identified. Which of the diagrams; represent chemically implausible situations has to be explained. Concept Information: Acid ionization constant K a : Acids ionize in water. Strong acids ionize completely whereas weak acids ionize to some limited extent. The degree to which a weak acid ionizes depends on the concentration of the acid and the equilibrium constant for the ionization. The ionization of a weak acid HA can be given as follows, HA (aq) → H + (aq) +A - (aq) The equilibrium expression for the above reaction is given below. K a = [ H + ][A - ] [ HA] Where K a is acid ionization constant, [ H + ] is concentration of hydrogen ion [ A - ] is concentration of acid anion [ HA] is concentration of the acid Diprotic and polyprotic acids: Acids having two or more hydrogen atoms are termed as diprotic or polyprotic acids. These acids lose one proton at a time by undergoing successive ionizations. For diprotic acids, the successive ionization constants are designated as K a 1 a n d K a 2 For triprotic acids, the successive ionization constants are designated as K a 1 , K a 2 a n d K a 3
