In the fountain experiment, dry hcl gas is filled in the round bottom flask |
|
Answer» tion:Demonstration: TAKE a dry round bottomed flask filled with dry HCl gas. Fix a two holed rubber cork on the mouth of round bottomed flask. ... It creates a low pressure inside the flask. But the pressure out side the flask being higher, pushes the blue litmus solution inside the flask with a great force and form a fountain.HCl gas PRESENT in the flask dissolves in water due to high solubility, creating a partial VACUUM in the flask. The outside pressure being higher pushes HCl gas present in the flask dissolves in water due to high solubility, creating a partial vacuum in the flask. The outside pressure being higher pushes the water up the jet TUBE which EMERGES as fountain.hope it's help mark as brainliest |
