Mō te Tellurium Dioxide
Ko te hua matua o te tahunga o te tellurium i te rangi ko te hauhā o te tellurium. Kāore e taea te wairewa i te hauhā o te tellurium i roto i te wai engari ka taea te wairewa katoa i roto i te waikawa whanariki kukū. Ka kitea te kore pumau o te hauhā o te tellurium ki te waikawa kaha me te waikura kaha. I te mea he mea amphoteric te hauhā o te tellurium, ka taea e ia te tauhohe ki te waikawa, ki te kawakore rānei i roto i te otinga.
I te mea he tino kaha te tūponotanga o te hauhā tellurium ki te whakapōrearea i te āhua o te tinana, ā, he paitini hoki, ina mimitihia ki roto i te tinana, ka puta he kakara (kakara tellurium) e rite ana ki te kakara o te kāriki i roto i te manawa. Ko tēnei momo mea ko te dimethyl tellurium i hangaia e te pākia o te hauhā tellurium.
