    Out of Cu2+ , Ni2+ , CO2+ and Mn2+, which is dissolved when H2S is passed through it in the presence of dil. HCl ?
  • Question 3/10
    4 / -1

    The only cations present in a slightly acidic solution are Fe3+ , Zn2+ and Cu2+ . The reagent that when added in excess to this solution would identify and separate Fe3+ in one step is
  • Question 4/10
    4 / -1

    The dark blue colour of the solution formed when excess of ammonia is added to a solution of copper (II) sulphate is due to the presence of the ion

  • Question 5/10
    4 / -1

    A solution of a metal ion when treated with KI gives a red precipitate which dissolves in excess KI to give a colourless solution. Moreover, the solution of metal ion on treatment with a solution of cobalt (II) thiocyanate gives rise to a deep blue crystalline precipitate. The metal ion is
