The diagram shows an apparatus for the laboratory preparation of hydrogen chloride. What does this method of collection tell you about the density of hydrogen chloride?

Hydrogen chloride is collected by the upward displacement of air since it is 1 . 28 times heavier than air. This shows that hydrogen chloride is denser than air.

The diagram given below shows the laboratory preparation of hydrogen chloride gas: Name the substance A that is added from the thistle funnel.

Hydrogen chloride is prepared in the laboratory by heating sodium chloride with concentrated sulphuric acid. A is concentrated sulphuric acid. The concentrated sulphuric acid is poured through the thistle funnel into a flask with NaCl . Reaction proceeds and HCl gas is liberated on heating. NaCl + H 2 SO 4 → Below 200 ∘ C NaHSO 4 + HCl

Certain blank spaces are left in the following table and these are labelled as A , B , C , D and E . Identify each of them. Lab preparation Reactants used Products formed Drying agent Method of collection (i) H C l gas N a C l + H 2 S O 4 A Concentrated H 2 S O 4 B (ii) N H 3 gas C M g O H 2 + N H 3 D E

The completed table is: Lab preparation Reactants used Products formed Drying agent Method of collection (i) H C l gas N a C l + H 2 S O 4 NaHSO 4 + HCl Concentrated H 2 S O 4 Upward displacement of air (ii) N H 3 gas Mg 3 N 2 + H 2 O M g O H 2 + N H 3 Quick lime Downward displacement of air
