Describe an experiment to prove the following:
(i) HCl gas is heavier than air.
(ii) HCl gas is highly soluble in water.
(iii) HCl gas contains the element chlorine.

Q. When

H C l

gas is passed through a saturated

N a C l

solution, the ionic product of

N a C l

is exceeded because of:

Q. When

H C l_{(g)}

is passed through a saturated solution of common salt, pure

N a C l

is precipitated because:

HCl gas is highly soluble in water.

HCl gas is covalent and NaCl is an ionic compound. This is because:

The correct option is C electronegativity difference between H and Cl is less than 2.1HCl gas is covalent and NaCl is ionic as the electronegativity difference between H and Cl is less than 2.1 .

$H C l$ gas is covalent and $N a C l$ is an ionic compound. This is because:

The correct option is C electronegativity difference between $H$ and $C l$ is less than $2.1$
$H C l$ gas is covalent and $N a C l$ is ionic as the electronegativity difference between $H$ and $C l$ is less than 2.1 .
