Explanation Vinegar contains approximately 5 % of acetic acid ( K a = 1.8 × 10 − 5 ) . Lemon juice contains approximately 1 % of citric acid ( H 3 C 6 H 5 O 7 ) . Lactic acid ( C 3 H 6 O 3 , K a = 1.4 × 10 − 4 ) is a 100 % pure molecular acid. The neutralization reaction can be written as given below. H 3 O + ( a q ) + H C O 3 − ( a q ) ⇌ H 2 C O 3 ( a q ) + H 2 O ( l ) The equilibrium constant is given below. K = 1 K a , H 2 C O 3 = 1 4.3 × 10 − 7 = 2.3 × 10 6 . As lactic acid, acetic acid and citric acid each presumably have K a > 10 − 7 , the three neutralization reactions will be product favored as K > 1. The general neutralization reaction can be written as shown below. H A ( a q ) + H 2 O ( l ) ⇌ H 3 O + ( a q ) + A − ( a q ) K a , H A So it is needed to determine which sample provides the largest number of H 3 O + ions. If one gram of lactic acid reacts, the number of moles of H 3 O + ions will be available is given below. 1 g C 3 H 6 O 3 × 1 m o l C 3 H 6 O 3 90.08 g C 3 H 6 O 3 × 1 m o l H 3 O + 1 m o l C 3 H 6 O 3 = 0
