Süsinikdioksiidi reageerimine leelisega
Süsinkdioksiid-CO on happeline oksiid, millel on omadus reageerida alustega.
Selles katses juhiti süsinkdioksiidi plastpudelisse, mille põhjas oli kümmekond milliliitrit kontsentreeritud kaaliumhüdroksiidi-KOH vesilahust. Pudel suleti tihedalt korgiga. Süsinikdioksiid neeldus (reageeris) KOH lahuses:
CO+2KOHKCO+HO
Gaasi hulk ning seega ka rõhk suletud nõus vähenes, suurem välisrõhk surus plastpudeli kokku.
