3-tajriba. Piridinning eruvchanligi va uning asoslik xossasi. 
Reaktivlar: Piridin, qizil lakmus qog`ozi, temir uch xloridning l% li eritmasi. 
Eslatma: Piridin ishtirokidigi reaksiyalar mo`rili shkafda bajarilishi lozim, chunki u o`ziga 
xos qo`lansa hidli modda 
Probirkaga 5-6 tomchi piridin solib ustiga 5-6 tomchi suv qo`shamiz. Bunda tiniq eritmaga hosil 
bo`ladi. Ustiga yana 5-10 tomchi suv qo`shing. Probirkada qanday jarayon kuzatildi?

Piridinning suv bilan yaxshi aralashishiga quyidagi sabab bo`ladi. Piridin molekulasidagi azot 
atominig elektronlari halqaning elektron buluti bilan mustahkam bog`lanib turadi. Azot ana shu 
elektron juftlari hisobiga protonni biriktirib oladi va oqibatda asos hosil bo`ladi.
