sodium peroxide (NaHSO4.H2O), which dehydrates on warming. If heated
strongly the pyrosulfate (Na2S2O7) is formed, which decomposes to give the
sulfate and sulfur(VI) oxide. Sodium hydrogensulfate is used as a cheap source
of sulfuric ...

Hazmat Chemistry Study Guide (Second Edition)
However, when we get to sodium peroxide (Na2O2), the formula doesn't seem to
make sense. “Peroxide” signals two atoms of oxygen. So if a single ion of oxygen
has a charge of 2- and the sodium ion has a net charge of +, shouldn't the ...
