Hello mate! Please mark as the brainliest.
Explanation:
Acetic acid present in vinegar will readily react with baking soda (sodium bicarbonate) to form sodium acetate with the effervescence of carbon dioxide. The equation for the reaction is: CH3COOH + NaHCO3 = CH3COONa + CO2 + H2O.
Answer:
Baking soda and vinegar react chemically because one is a base and the other is an acid. Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic acid.
The baking soda and vinegar reaction is actually two separate reactions. The first reaction is the acid-base reaction.
When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate.
The second reaction is a decomposition reaction. The carbonic acid formed as a result of the first reaction immediately begins to decompose into water and carbon dioxide gas.
Acetic acid present in vinegar will readily react with baking soda (sodium bicarbonate) to form sodium acetate with the effervescence of carbon dioxide.
The chemical equation for the overall reaction is:
NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)
The chemical reaction actually occurs in two steps as said earlier. First, there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:
H2CO3 → H2O + CO2
