Articles Required : A strong solution of ammonia water, a beaker, stove or heater.
If you don't believe it, try this experiment. Take a beaker or any other glass-vessel which won't break on a heater. Fill three-fourths of it with the strong solution of ammonia water. Now the moment you put it on the heater, almost immediately bubbles start rising from the bottom of the liquid to its surface. Can any liquid boil so fast? Would you believe it? No! Then what happens in this case ? Why do bubbles form ?
All this happens because you have a very strong ammonia solution and it means that water contains a great deal of ammonia. Thus when it's heated it's unable to contain all the ammonia gas any more. So, as the temperature rises the ammonia emerges out of it in the form of bubbles, and you get the impression that the solution is about to boil.
When you put water in a pot to make tea, what's the indication that it's about to boil ? The bubbles! Isn't it? But be careful! Whenever the bubbles are seen that doesn't mean that the liquid is about to boil. This phenomenon is true only within the boundary of your kitchen.
