Mention the easy test method to estimate the mercerizing effect.

the easy test method to estimate the mercerizing effect described bellow

After mercerization we need to test the effect of mercerization on textile fibre. We can estimate this by Easy-Test method. The easy-test method is described below:
Ø   At first take 10ml of 0.25N Ba (OH) 2 in a beaker, then titration with 0.1N HCl and methyl orange as an indicator.
Ø   At the end point yellow color solution changes to pink color solution and then the titration is completed.
Ø   The measure the amount of HCl used for titration, Let HCl= x ml
Ø   Now take 2gm of mercerized sample
Ø   Then the sample is immersed into the 30ml of 0.25N Ba (OH)2 solution for 4hoursand then taken out.
Ø   Then take 10ml of left out Ba (OH)2 solution by pipette in a beaker.
Ø   Now titration with 0.1N HCl and methyl orange as an indicator.
Ø   The measure the amount of HCl used for titration, Let HCl= y ml
