In qualitative analysis, in order to detect second group basic radical, gas is passed in the presence of dilute HCl to
Increase in dissociation of
Decrease the dissociation of salt solution
Decrease the dissociation of
Increase the dissociation of salt solution
being a strong acid suppresses ionisation of the weak acid
. This results in a lesser
which is sufficient to cause the precipitation of the sulphides of Group II radicals exceed their corresponding solubility product and hence only these are precipitated.
Hence, the correct answer is Option (3)
