what is the gas formed when baking soda is added to vinegar?
complete the reaction:
NaHCO3(s) + CH3COOH(aq)
NaHCO3 + CH3COOH ==> H2O + CO2 + CH3COONa
When baking soda (sodium bicarbonate, NaHCO3) is added to vinegar (acetic acid, CH3COOH), a chemical reaction occurs. This reaction is known as an acid-base reaction or a double displacement reaction. The products of this reaction are carbon dioxide gas (CO2), water (H2O), and sodium acetate (CH3COONa).
To understand why carbon dioxide gas is formed in this reaction, we need to consider the reaction equation.
The complete reaction can be written as:
NaHCO3(s) + CH3COOH(aq) → CO2(g) + H2O(l) + CH3COONa(aq)
To balance the equation, we need to ensure that we have the same number of atoms on both sides. In this case, the equation is already balanced.
To find the gas formed when baking soda is added to vinegar, we look at the product side of the equation. In this case, carbon dioxide gas (CO2) is produced.
So, the gas formed is carbon dioxide (CO2).
