Answer:
On passing hydrogen gas through soap solution it does not get dissolved in it, and the solution easily form bubbles containing hydrogen gas. The presence of hydrogen gas can be tested with the help of a burning splinter near the bubbles. Therefore, soap solution can be used in testing of hydrogen gas.
