Rubidium hydrogen sulfate
chemical compound
Rubidium hydrogensulfate, sometimes referred to as rubidium bisulfate, is the half neutralized rubidium salt of sulfuric acid. It has the formula RbHSO4.
Properties
It is a hygroscopic compound.
Its crystals are isomorphs with ammonium hydrogensulfate crystals.
Its enthalpy of solution is 15.62 kJ/mol.
After warming up it decomposes to rubidium disulfate and water:
2 RbHSO4 → Rb2S2O7 + H2O
Synthesis
It may be synthesised with water and a stoichiometric amount of rubidium disulfate. Reaction takes place where there is no humidity:
Rb2S2O7 + H2O → 2 RbHSO4
There is another method of creation. It is similar to the synthesis of sodium sulfate and potassium sulfate. This reaction requires rubidium chloride and a little bit of warm sulfuric acid. Some hydrogen chloride is also produced during the reaction.
The public source identifies “Rubidium hydrogen sulfate” as chemical compound. This brief keeps that definition visible, then builds a research path around Rubidium, hydrogen and sulfate.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Rubidium hydrogen sulfate”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q2171589. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
