Question

What will happen if you take teaspoonful of vinigar added with A Pinch of soda and pass the gas through freshly prepared lime water? discuss

Answer 1

Answer:

The lime water turns milky

CH3COOH + NaHCO3 →CH3COONa+H2O+CO2↑

(acetic acid) (sodium bi. (sodium carbonate) acetate)

CO2 + Ca(OH)2 → CaCO3 + H2O

( lime water)

Explanation:

When vinegar reacts with sodium bicarbonate it results in the formation of sodium acetate, water & evolution of CO2 gas. This CO2 evolution is the reason for a hissing sound and bubble formation.

When this CO2 is passed through lime water, this turns lime water to milky in color. This is due to the formation of CaCO3.
