Reaktivlar: a) 5% li kumush nitrat eritmasi, b) 1% li glyukoza, d) 10% li ammiak.
Ishning bajarilishi: probirkaga 1 ml 5% li kumush nitrat eritmasidan solinadi va ustiga tomchilatib ammiak eritmasidan qo'shiladi. Avvaliga kulrang cho‘kma hosil bo'ladi va ammiak yana qo'shilishi natijasida erib ketadi. Kumush nitratning ammiakli eritmasiga 2-3 ml glyukozadan qo'shiladi. Probirkalar 80°C li suvga 5-10 minutga qo'yiladi. Shundan keyin probirka devorida kumush metalining ko'zguga o'xshash cho'kmasi hosil bo'ladi.
