Aim: To investigate the reaction between sodium bicarbonate powder and ethanoic acid and discover the concept of limiting reagents.
Independent: Mass of sodium bicarbonate (NaHCO3)
Dependent: Volume of carbon dioxide gas (CO2)
Controlled: Ethanoic Acid (CH3COOH)
NaHCO3 + CH3COOH = CH3COONa + H2O + CO2
Raw data table
As conical flask is swirled, tube containing NaHCO3 falls into the ethanoic solution. Large bubbles appear and the solution produces white foam. After a few minutes, bubbles stop appearing and solution in the conical flask turns clear. No heat or sound was observed.
