Look up the active ingredient in baking soda. Write a molecular and net ionic equation when that active ingredient is mixed with

Volgvan

Answer:

The active ingredients in baking soda (NaHCO3) are

$Na^+$ and $HCO3^-$

when Baking soda reacts with Acetic acid

Molecular equation

NaHCO3(aq) + CH3COOH(aq) → Na(CH3COO)(aq) + CO2(g) +H2O(l)

Ionic equation

$Na^+ + HCO3^- + CH3COOH$ → $Na^+ + CH3COO^- +CO2 + H2O$

as $Na^+$ is present on both sides so it will cancel out and the net ionic equation will be

$HCO3^-(aq) + CH3COOH(aq)$ → $CH3COO^-(aq) + CO2(g) + H2O(l)$
