Elektrolit Sn(OH)2 ima:

Kiseli karakter
Bazni karakter
Amfoterni karakter
Neutralni karakter

U reakciji:

Pb(NO3)2 + 2NH4OH → Pb(OH)2 + 2NH4NO

dolazi do:

Formiranja taloga bele boje koji potiĝe od Pb(OH)2
Formiranja taloga bele boje koji potiĝe od NH4NO3

Prilikom oksido-redukcione reakcije:

3SnCl2 + 2K2CrO4 +16HCl → 3SnCl4 + 2CrCl3 + 8H2O + KCl

dolazi do promene:

Boje rastvora u zelenu
Boje rastvora u žutu
Obezbojavanja rastvora
Formiranja taloga bele boje

Izraziti 0,1% u ppb
