Sodium metabisulfite ke phofo e tšoeu kapa e mosehla e kristale kapa kristale e nyane e nang le monko o matla oa SO2. Tharollo ea eona ea metsi e na le asiti 'me e ntša SO2 ha e kopana le li-acid tse matla, e hlahisang letsoai le tsamaellanang. Haeba e siuoa moeeng nako e telele, e fetoha oxidize ho Na2S2O6, kahoo sehlahisoa sena se ke ke sa bolokoa nako e telele.
