Question

acetic acid was added to a solid x kept in a test tube A colourless gas odourless gas Y has evolved.the gas was passed through lime water which turned milky;name X and Y and write the chemical reaction

Answer 1

hey ,this is ur answer

Answer 2

The compound X and gas Y are identified as $(NaHCO_3)$ and $(CO_2)$ respectively.

Explanation:

• When acetic acid ($CH_3COOH$) reacts with sodium hydrogen carbonate   ($NaHCO_3$) the following reaction occurs:

$CH_3COOH + NaHCO_3\rightarrow CH_3COONa + CO_2+H_2O$

• From the above reaction, it is clear that the gas formed is carbon dioxide which is colorless, odourless, and turns lime water milky.
• As gas Y given in the question has the same characteristics, thus gas Y is identified as Carbon dioxide.
• As acetic acid reacts with sodium hydrogen carbonate and leads to the production of carbon dioxide, therefore Solid X is identified as Sodium hydrogen carbonate.
• Thus it can be inferred that:

Solid X - Sodium hydrogen carbonate ($NaHCO_3$)

Gas Y - Carbon dioxide ($CO_2$)
