1. PEMERIKSAAN ASAM SULFAT METODE ALKALIMETRI

Reagen

a. NaOH 100ml

BM x N x volml x1000

= 40 x0,05N x100ml

1x 1000

= 0,2034 gram NaOH + Aquadest add 100 ml

b. PP 1% 50 ml

=: 1gram100ml x 50 ml

= 0,5011 gram / 50 ml etanol 96%

2. PEMERIKSAAN ASAM LEMAK METODE SOHXLET

Reagen

a. Eter 75 ml

b. HCl 25% 55 ml

25 %37 %

x 55 ml = 37, 162 ml

55ml=37,162ml=17,838mlaquadest

= 8,919 aquadest

c. AgNO3 0,1 M 200 ml

gram : M x Vol x BM

: 0,1 x 167,87 x 55/1000 = 1,84657 gram

: 1,84657 gram AgNO3 + Aquadest add 200 ml
