A question in GATE 2012 Textile Engineering and Fibre Science Paper with Solution has been updated:

In an experiment, 1 g each of the mercerized and unmercerized fabric samples are separately treated in 30 ml of 0.25N barium hydroxide solution for the required time. 10 ml of these solutions are drawn and titrated against 0.1N HCl solution. The volumes of HCl consumed at the end of these titrations are m for mercerized and u for unmercerized cases. If Barium Activity Number (BAN) = [(b-m)/(b-u)] x 100, where m = 18 ml, u = 20 ml and b is the volume of HCl consumed in the blank titration, then the BAN value for the above mercerized sample is _______.

  1. 160
  2. 110
  3. 120
  4. 140
