What is the balanced chemical equation of Acetic Acid and Sodium Bicarbonate that...
1 Answer | add yours
- CH3CO2H + NaHCO3 = CH3CO2Na + H2CO3
- H2CO3 = H2O + CO2 (gas)
- Ca(OH)2 + CO2 = CaCO3 + H2O
- CaCO3 + CO2 + H2O = Ca(HCO3)2
Best answer as selected by question asker.
Acetic acid and Sodium bicarbonate react, to form sodium acetate and carbonic acid, which is very unstable and decomposes instantaneously to produce CO2 and H2O. When this gas is passed through clear lime water, which contains Ca(OH)2, insoluble CaCO3 is formed which turns lime water milky. When the gas is passed in excess the solution turns clear again owing to the formation of relatively more soluble Ca(HCO3)2. This is the basis for lime water test for CO2. The balanced chemical equations are as follows:
