When I doing an experiment that study the effect of temperature on the rate of reaction, I used a delivery tube to transfer the gas produced to another test tube that filled with distilled water. The bubble formed. It looked like the water form a membrane around the gas.How this formed? ???

The bubble formed inside the distilled water? Maybe it was caused by the byproduct of the reaction.

Maybe you can tell us more about the chemicals used and the diagram of the experiment.

i think wt he want to know is that why we blow gas into water or sth, bubbles form
i think this is a suitable metaphor for u to understand
when we put a hand in water gently, the water will surround your hand and finally fully 'wrapped' the hand.
same for a gas bubble
like a certain amount of gas is 'pushed' or 'blew' towards a sink of water, then the water wrapped the gas same as the hand, but for gas case water fully wrapped the gas and that 's what a bubble is!

A remarkable video of bubbles in "zero" gravity (see alka seltzer @ 2:00)...
