Question

a student was studying the action of acetic acid on sodium carbonate he was also planning to study the action of gas evolved on limestone but he found that the gas bubbles do not pass through limewater what could be the reason

Answer 1

Physical properties of acetic acid:

1. It solidifies amid winters, as its liquefying point is 290 K.
2. It has a trademark vinegar-like scent.

At the point when a spot of sodium hydrogen carbonate is added to acidic corrosive in a test tube, an energetic foam is seen because of development of a rapid and unscented carbon dioxide gas, CO2. This gas when gone through lime water turns it smooth because of arrangement of calcium carbonate, CaCO3. Compound conditions for the response:

CH3COOH(aq) + NaHCO3(s) ------> CH3COONa (aq) + H2O(l) + CO2(g) Ca(OH)2(aq) + CO2(g) ------>CaCO3(s) + H2O(l)
