Xisaabi boqolkiiba ammonium sulfate [(NH4)2SO4] ee ku jira Tusaalaha la qaaday:
Natiijadu = [(BV) × N × F ×100]/W
B = 1 N sulfuric acid VS uu isticmaalo Bannaanka (mL)
V = 1 N sulfuric acid VS oo uu isticmaalo Tusaalaha (mL)
N = caadinimada dhabta ah ee titrant dhabarka (mEq/mL)
F = qodob u dhigma, 66.07 mg/mEq
W = miisaanka Tusaalaha (mg)

Falanqaynta
[Fiiro gaar ah- Tijaabada Muunadda iyo Xakamaynta waxaa lagu door bidayaa in lagu sameeyo tuubooyinka isbarbardhigga midabka.]
Ku mil muunada 25 mL oo ah 0.5 N sulfuric acid, ku dar 1 ml mid kasta oo ah reagent Fosfate A iyo Fosfate reagent B, una ogolow inaad ku istaagto heerkulka qolka 2 saacadood.Ku sii wad kontoroolka adiga oo isticmaalaya tiro isku mid ah reagents isku mid ah sida tijaabada Tusaalaha.
Shuruudaha aqbalaadda: Midab kasta oo buluug ah oo laga helo Tusaha waa inuusan dhaafin kan laga soo saaray Xakamaynta (NMT 5 ppm).
• Chloride iyo Sulfate, Chloride <221>
