CdS precipitates.
group 2 cation salts have low solubility product.When the cadmium chloride solution is saturated with H2S in acidic medium due to common ion effect concentration of S2-
decreases .thus it offers small ionic product just to overcome the solubility product of group 2 salts.
According to le chatliers principle the reaction then shifts to backward direction and CdS precipitates out from solution. Hope it helps if you find it helpful kindly mark brainliest
