When dilute HCl is added to a salt Q, a brisk effervescence is produced and the gas turns lime water milky.
When NH4OH solution is added to the above mixture (after adding dilute HCl), it produces a white precipitate which is soluble in excess NH4OH solution.
How is the gas collected and why?
Describe an experiment to prove the following:
HCI gas is heavier than air.
Choose the correct answer from the options given below: HCl gas can be prepared by direct combination of hydrogen and chlorine gas in presence of
How will you show that hychloric acid contains both hydrogen and chlorine (other than by electrolysis) ?
Hydrogen chloride gas is very soluble in water. It is dissolved in water to prepare hydrochloric acid by using an anti-suction device, as shown in the diagram. Very briefly explain how this device prevents the suction of water into the flask, in which hydrogen chloride gas is produced.
The diagram shows an apparatus for the laboratory preparation of hydrogen chloride.
