M g ( O H ) 2 ( s ) + 2 H 3 O + ( a q ) → M g 2 + ( a q ) + 4 H 2 O ( l ) The molar ratio of antacid and the acid is 1 : 2. The moles of stomach acid that is neutralized by 1 g of milk of magnesia can be calculated as given below. 1 g M g ( O H ) 2 × 1 m o l M g ( O H ) 2 58.3196 g M g ( O H ) 2 × 2 m o l H 3 O + 1 m o l M g ( O H ) 2 = 0.03 m o l H 3 O + Calcium carbonate: The neutralization reaction of calcium carbonatewith stomach acid is given below. C a C O 3 ( s ) + 2 H 3 O + ( a q ) → C a 2 + ( a q ) + 3 H 2 O ( l ) + C O 2 ( g ) The molar ratio of antacid and the acid is 1 : 2.
