Show with the help of chemical & word equation the chemical reaction between (a) Vinegar and baking soda. (b) Carbon dioxide and lime water.
Answers
Answer:
(a) Vinegar and baking soda.
The overall chemical reaction between baking soda (sodium bicarbonate) and vinegar (weak acetic acid) is one mole of solid sodium bicarbonate reacts with one mole of liquid acetic acid to produce one mole each of carbon dioxide gas, liquid water, sodium ions, and acetate ions.
The reaction proceeds in two steps. The first reaction is a double displacement reaction, while the second reaction is a decomposition reaction.
The baking soda and vinegar reaction can be used to produce sodium acetate, by boiling off or evaporating all the liquid water.
(b) Carbon dioxide and lime water.
CaCO3 +H20This means that the carbon dioxide and limewater react to produce calcium carbonate and water. ... CO2(g) + Ca(OH)2(aq) -----> CaCO3(s) + H2O(l)The white milky suspension/precipitate is caused by the formation of calcium carbonate and explains the limewater test for carbon dioxide.
In its equation form that makes: CO2 + Ca (OH)2 -----> ? CO2 + Ca(OH)2 —-> CaCO3 + H2O
