1.H2S\mathrm{H_2S}H2S in the presence of HCl precipitates cations in group II but not group V because:a.HCl activates H2S\mathrm{H_2S}H2Sb.HCl increases concentration of Cl−\mathrm{Cl^-}Cl−c.HCl decreases concentration of S2−\mathrm{S^{2-}}S2−d.HCl lowers the solubility of H2S\mathrm{H_2S}H2SLogin to continueOnly logged in users canattempt or see the solution.
