Problem: Baking soda (sodium bicarbonate, NaHCO3) reacts with acids in foods to form carbonic acid (H2CO3), which in turn decomposes to water and carbon dioxide gas. In a cake batter, the CO2(g) forms bubbles and causes the cake to rise.A rule of thumb in baking is that 1/2 teaspoon of baking soda is neutralized by one cup of sour milk. The acid component in sour milk is lactic acid, CH3CH(OH)COOH. Write the equation for this neutralization reaction.

FREE Expert Solution

We are asked to write the equation for the neutralization reaction.


We are given the Reactants: 

NaHCO3 (aq)+ CH3CH(OH)COOH(aq) 


The reactants split into ions:

NaHCO3(aq)  → Na+(aq) + HCO3(aq)

CH3CH(OH)COOH(aq) → CH3CH(OH)COO(aq)+ H+(aq)
