Question

The chemical equation for the reaction of baking soda (sodium bicarbonate, nahco3) and vinegar (acetic acid, ch3cooh) may be written as two steps. fill in the missing information for the chemical equation. step 1: _____ + _____ → ch3coona(aq) + h2co3(l) step 2: h2co3(l) → h2o(l) + _____.

Answer 1

Answer;

Step 1;  NaHCO3(s) + CH3COOH(l)

Step 2 ; CO2(g)

Explanation;

• The chemical equation for the reaction of baking soda (sodium bicarbonate, NaHCO3) and vinegar (acetic acid, CH3COOH) reaction occurs in two steps.

Step 1;  

• A double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
• Equation;

NaHCO3(s)+ CH3COOH(l) → CH3COONa(aq) + H2CO3(l)

Step 2;

• Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:

H2CO3(l) → H2O(l) + CO2(g)
