Will you please provide me the Ordnance Factory Chargeman Model question paper??? This is the Ordnance Factory Chargeman Model question paper: 10. Non-aqueous ionizing solvents can sometimes be used in acidimetry and alkalimetry. In which one can the solvent encourage the loss of proton from a weak acid making it effectively much stronger ? (1) Polar solvent (2) Non-polar solvent (3) Acidic solvent (4) Basic solvent 11. The following indicator solution is called as adsorption indicator : (1) Tartrazine (2) Fluorescein (3) Methyl red (4) None of the. above 12. Primary standard solution should contain a substance which is (1) highly pure (2) stable in air (3) more soluble in water (4) All of the above 13. If the precipitate is a salt of weak acid and strong base and is slightly soluble, it may exhibit a tendency to hydrolyse and the soluble product of hydrolysis will be a (1) base (2) acid (3) neutral (4) polar 14. Washing of precipitate in gravimetric analysis is more advantageous if precipitate is washed with given amount of solvent with (1) more amount of solvent each time but less number of washing (2) less amount of solvent each time but more number of washing (3) one washing with all the solvent (4) None of the above Rests of the questions are in the attachment, please click on it……..
