Name the drying agent used to dry HCl gas.
How is the gas collected and why?
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.
Give reason for the following:
Dilute hydrochloric acid cannot be concentrated by distilling (boiling) the dilute acid.
Dilute hydrochloric acid is added in turn to a mixture of iron and sulphur and to the compound formed between iron and sulphur. Name the gas formed in each case.
The diagram shows an apparatus for the laboratory preparation of hydrogen chloride.
(i) Identify A and B
(ii) Write the equation for the reaction
(iii) How would you check whether or not the gas jar is filled with hydrogen chloride?
(iv) What does the method of collection tell you about the density of hydrogen chloride.
The aim of the fountain experiment is to prove that
- Name the experiment illustrated below.
- State the colour of the water that has entered the round-bottomed flask.
What property of hydrogen chloride is demonstrated when it is collected by downward delivery (Upward displacement)?
State the following:
The drying agent used in the laboratory preparation of HCl gas.
