Which gas will be evolved if Sodium bicarbonate is added to a solution of Tartaric acid. How will you test this gas?
You should get carbon dioxide (CO2). Combining sodium bicarbonate to tartaric acid will yield water-soluble sodium tartrate and carbonic acid. Carbonic acid (H2CO3) will instantly decompose into water and carbon dioxide. Collect the gas, pour it over a lit candle flame. The flame will go out, proving that it's CO2. sodium bicarbonate and Tartaric acid together in dry form are baking powder.
