A gas is liberated immediately with brisk effervescence when you add acetic acid to sodium hydrogen carbonate powder in a test tube. Name the gas and describe a test to confirm the identity of the gas.

Text Solution

Verified by Experts

The gas evolved is `CO_(2)` (For reaction, consult Q. 19). It turns lime water milky when bubbled in small amount. On bubbling the gas in excess, the milkiness disappears.
