The percent ionization of the solution prepared by the dissolution of phenol with given concentration is to be determined. Concept introduction: The ionization of the weak acid takes place as HA ( aq ) + H 2 O ( l ) ⇌ H 3 O + ( aq ) + A − ( aq ) K a is the measure of dissociation of an acid and is known as acid-ionization constant, which is specific at a particular temperature. K a = [ H 3 O + ] [ A − ] [ HA ] …… (1) Percent ionization is the percentage of acid that gets dissociated upon addition in water. It depends on the hydronium ion concentration. % ionization = [ H 3 O + ] eq [ HA ] o × 100 % …… (2) Here, [ H 3 O + ] eq is the hydronium ion concentration at equilibrium and [ HA ] o is the original acid concentration. Solution : (a) 0.0015 % (b) 0.0023 % (c) 0.89 % a) 0.56 M. Refer Table 16.6 for the acid ionization constant of phenol as K a = 1.3 × 10 − 10 . When a weak acid is dissolved in water, only partial dissociation takes place into H 3 O + ions and its conjugate base. Thus, the concentration of H 3 O + is determined by K a of the acid. The reaction of the weak acid ( C 6 H 5 OH ) is as follows: C 6 H 5 OH( a q ) + H 2 O( l ) ⇌ H 3 O + ( a q ) + C 6 H 5 O − ( a q ) Prepare an equilibrium table and represent each species in terms of x as: C 6 H 5 OH ( aq ) H 2 O ( l ) H 3 O + ( aq ) C 6 H 5 O − ( aq ) Initial concentration ( M ) 0.56 − 0 0 Change in concentration ( M ) − x − + x + x Equilibrium concentration ( M ) 0.56 − x − x x Now, substitute these concentrations in equation (1) as: K a = [ H 3 O + ] [ A − ] [ HA ] K a = ( x ) ( x ) ( 0.56 − x ) Since the value of K a is very small, the amount of acid dissociated is less. Therefore, ( 0.56 − x ) can be approximated as 0.56 . Now, substitute the value of K a in the above equation as: 1.3 × 10 − 10 = ( x ) ( x ) 0.56 x 2 = ( 1.3 × 10 − 10 ) 0.56 x = 7.28 × 10 − 11 x = 8.5 × 10 − 6 Thus, [ H 3 O + ] = 8.5 × 10 − 6 M Calculate the percent dissociation from equation (2) as: % ionization = [ H 3 O + ] eq [ HA ] o × 100 % % dissociation = 8.5 × 10 − 6 0 .56 × 100 % = 0.0015 % Since the percent dissociation is less than 5 % , the approximation is valid. Therefore, the percent dissociation is 0.0015 % . b) 0.25 M. Refer Table 16.6 for the acid ionization constant of phenol as K a = 1.3 × 10 − 10 . When a weak acid is dissolved in water, only partial dissociation takes place into H 3 O + ions and its conjugate base. Thus, the concentration of H 3 O + is determined by K a of the acid. The reaction of the weak acid ( C 6 H 5 OH ) is as follows: C 6 H 5 OH( a q ) + H 2 O( l ) ⇌ H 3 O + ( a q ) + C 6 H 5 O − ( a q ) Prepare an equilibrium table and represent each species in terms of x as: C 6 H 5 OH ( aq ) H 2 O ( l ) H 3 O + ( aq ) C 6 H 5 O − ( aq ) Initial concentration ( M ) 0.25 − 0 0 Change in concentration ( M ) − x − + x + x Equilibrium concentration ( M ) 0.25 − x − x x Now, substitute these concentrations in equation (1) as: K a = [ H 3 O + ] [ A − ] [ HA ] K a = ( x ) ( x ) ( 0.25 − x ) Since the value of K a is very small, the amount of acid dissociated is less. Therefore, ( 0.25 − x ) can be approximated as 0.25 . Now, substitute the value of K a in the above equation as: 1.3 × 10 − 10 = ( x ) ( x ) 0.25 x 2 = ( 1.3 × 10 − 10 ) 0.25 x = 3.25 × 10 − 11 x = 5.7 × 10 − 6 Thus, [ H 3 O + ] = 5.7 × 10 − 6 M Calculate the percent dissociation from equation (2) as: % ionization = [ H 3 O + ] eq [ HA ] o × 100 % % dissociation = 5.7 × 10 − 6 0 .25 × 100 % = 0.0023 % Since the percent dissociation is less than 5 % , the approximation is valid. Therefore, the percent dissociation is 0.0023 % . c) 1.8 × 10 − 6 M . Refer Table 16.6 for the acid ionization constant of phenol as K a = 1.3 × 10 − 10 . When a weak acid is dissolved in water, only partial dissociation takes place into H 3 O + ions and its conjugate base. Thus, the concentration of H 3 O + is determined by K a of the acid. The reaction of the weak acid ( C 6 H 5 OH ) is as follows: C 6 H 5 OH( a q ) + H 2 O( l ) ⇌ H 3 O + ( a q ) + C 6 H 5 O − ( a q ) Prepare an equilibrium table and represent each species in terms of x as: C 6 H 5 OH ( aq ) H 2 O ( l ) H 3 O + ( aq ) C 6 H 5 O − ( aq ) Initial concentration ( M ) 1.8 × 10 − 6 − 0 0 Change in concentration ( M ) − x − + x + x Equilibrium concentration ( M ) ( 1.8 × 10 − 6 ) − x − x x Now, substitute these concentrations in equation (1) as: K a = [ H 3 O + ] [ A − ] [ HA ] K a = ( x ) ( x ) ( ( 1.8 × 10 − 6 ) − x ) Since the value of K a is very small, the amount of acid dissociated is less. Therefore, ( ( 1.8 × 10 − 6 ) − x ) can be approximated as 1.8 × 10 − 6 . Now, substitute the value of K a in the above equation as: 1.3 × 10 − 10 = ( x ) ( x ) 1.8 × 10 − 6 x 2 = ( 1.3 × 10 − 10 ) ( 1.8 × 10 − 6 ) x = 2.34 × 10 − 16 x = 1.6 × 10 − 8 Thus, [ H 3 O + ] = 1.6 × 10 − 8 M Calculate the percent dissociation from equation (2) as: % ionization = [ H 3 O + ] eq [ HA ] o × 100 % % dissociation = 1.6 × 10 − 8 1 .8 × 10 − 6 × 100 % = 0.89 % Since the percent dissociation is less than 5 % , the approximation is valid. Therefore, the percent dissociation is 0.89 % .
