# 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)
