  • Question 1/10
    4 / -1

    Aqueous solution of a salt when treated with AgNO3 solution gives a white precipitate, which dissolves in NH4OH. Radical present in the salt is:

    Solutions

    When Cl− , Br− and F− are treated with AgNO3 solution in presence of dilute HNO3, corresponding silver halide is obtained which is soluble in NH4OH, NaCN, and Na2 S2 O3 .

     

  • Question 2/10
    4 / -1

    Which of the following combines with Fe (II) ions to form a brown complex?

    Solutions

    Brown ring test with (FeSO4.. NO)

     

  • Question 3/10
    4 / -1

    Which of the following will not produce a precipitate with AgNO3 solution?

    Solutions

    With F− no precipitate is obtained because of low lattice energy of AgF, so it remains in ionized state

     

  • Question 4/10
    4 / -1

    Chromyl chloride vapours are dissolved in NaOH and acetic acid and lead acetate solution is added, then:

    Solutions


     

  • Question 5/10
    4 / -1

    A salt gives violet vapours when treated with conc. H2SO4 . It contains:

    Solutions

    Iodine vapours are violet

    ∴ The salt must contain I− as

     

  • Question 6/10
    4 / -1

    A salt is heated first with dil. H2SO4 and then with conc. H2SO4. No reaction takes place. It may be:

    Solutions

    The salt must have  group which is also present in the acid so reaction is not takes place.

     

  • Question 7/10
    4 / -1

    Nitrates of all the metals are:

    Solutions

    Nitrates and acetates of all metals are water soluble.

     

  • Question 8/10
    4 / -1

    Which of the following precipitate does not dissolve even in large excess of NH4OH ?

    Solutions

    AgCl and AgBr dissolve in NH4OH and form complexes but AgI doesn’t react with NH4OH. e.g.

     

  • Question 9/10
    4 / -1

    When CO2 is passed into lime water it turns milky. When excess of CO2 is passed, milkyness disappears because?

    Solutions

     

  • Question 10/10
    4 / -1

    A substance on treatment with dil H2SO4 liberates a colourless gas which produces A. turbidity with baryta water and B. turns acidified dichromate solution green. The reaction indicates the presence of:

    Solutions
