5.0 Procedure

5.1 Check the performance of apparatus by recovery from ammonium chloride.
5.2 Recovery from Ammonium Chloride.
5.2.1 Take 1.0698 gm (+ 0.001 gm ) of ammonium chloride (previously dried at 105oC for 4 hrs.) in 1N H2SO4 and dilute it to 1000 ml with 1 N H2SO4
5.2.2 Take 5 ml of above solution in kjedhal tube for distillation.
5.2.3 Collect distillate in received solution and Titrate it against 0.025 N HCl using methyl red, until the color change from green to pink.
5.2.4 Calculate the recovery and record it in Annexure - I .
5.3 Frequency: Once in three Month.

Set –1                                                                                  Set-2

Taken Wt. of Ammonium chloride : ___________ gm Taken Wt. of Ammonium chloride : _________gm

Blank B.R  : __________ ml                                                 Blank  B.R :__________ ml

Test B.R    : ___________ml                                                Test B.R    : ___________ml
Difference : ___________ml                                                  Difference : ___________ml

Calculation  :

Recovery : b x d x 1000

b is ml of 0.025 N HCl
d  is normality of 0.025 N HCl

                     =  ______________ %                                           =  _______________ %

Acceptance Criteria : Average recovery should be between 98.0 % to 102.0%.
