Answers
Answer: explained below
Explanation:
1. what happens to the mixture?
the mixture reacts and carbon dioxide gets released. it forms foam-ish substance and rapidly rises.
the chemical equation:
NaHCO3 + CH3COOH = CO2 + CH3COONa + H2O
2. give reason for the reaction
the reason is baking soda reacts with vinegar and releases carbon dioxide and water simultaneously. this is because the elements react rapidly.
3. put a tarnished metal item e.g. jewellery spoon etc.in the mixture and leave for 1 hour.what happens to the metal item?
the metal item's stain gets reduced as the product from the reaction removes the stain easily as it is acidic. with washing the spoon the metal will be as new as bought. this happens because of the carbon dioxide in the product.
