Situācija
Gaisa reģenerācijai zemūdenēs un citās slēgtās telpās izmanto Na2O2 un KO2 ,jo to reakcijā ar ogļskābo gāzi izdalās skābeklis:

2Na2O2 + 2CO2 2Na2CO3 + O2
4KO2 + 2 CO2 2 K2CO3 + 3O2

Problēma 1
2Na2O2 + 2CO2 2Na2CO3 + O2

Kā redzams no reakcijām, izmantojot nātrija peroksīdu, no 2 ogļskābās gāzes molekulām iegūst tikai 1 molekulu skābekļa – gaisa reģenerācija nenotiek pietiekošā apjomā un pēc laika iestājas skābekļa bads.…
