p2o5
is not used as drying agent for the preparation of hydrogen chloride gas .
hNoliition is not used for electronlating with silver​

Answer 1

Drying agents: Dry hydrogen chloride is collected by bubbling through conc. H

2

​

SO

4

​

.

Reason for not using P

2

​

O

​

and CaO drying agents:

Other drying agents like P

​

and CaO are not used because they react with HCl

2HCl+CaO→CaCl

Option D is correct.

Thus, done :))

Answer 2

Drying agents: Dry hydrogen chloride is collected by bubbling through conc. H2 SO 4

Reason for not using P

2O5

and CaO drying agents:

Other drying agents like P2O5

and CaO are not used because they react with HCl

2HCl+CaO→CaCl 2 +H 2O3HCl+P2 O 5 →POCl 3 +3HPO 3

Option D is correct.
