In test tune A , vinegar is an acid and baking soda is a base, so a precipitation reaction will take place.

In test tube B , zinc is a metal which is reacting with dil. Hydrochloric acid , forming zinc chloride and evolution of hydrogen gas. Presence of hydrogen gas can be checked by bringing a burning flame or a burning candle near it, if the gas burns with a pop sound, the. it is hydrogen.......

Answer 2

Answer:

6. (a) Carbon dioxide is released in test tube A.

        Hydrogen gas is released in test tube B.

6. (b) We do the test of mixing just enough vinegar (Acetic Acid) and baking soda (Sodium bicarbonate) which produces a brisk effervescence and produces carbon dioxide.

        A splint is lit and held near the opening of the tube, then the stopper is removed to expose the splint to the gas. If the gas is flammable, the mixture ignites. This test is used to identify hydrogen, which extinguishes with a pop sound.
