The Sulfurous Acid Solution 5-6% Analytical Grade ACS by Dinâmica, available at LojaLab, is an acidic aqueous sulfur-dioxide solution formally represented as H2SO3. The solution has reducing character and may consume oxidants in methods specifying sulfite or bisulfite chemistry.
Characteristics
- Acidic aqueous sulfur-dioxide solution formally identified as sulfurous acid
- Commercial 5-6% concentration in analytical/ACS grade
- Equilibrium system containing dissolved SO2, sulfurous acid, bisulfite and sulfite
- Reducing character and sensitivity to oxidation by atmospheric oxygen
- CAS 7782-99-2 and formal molar mass 82.08 g/mol for H2SO3
Applications
- Preparation of reducing media and consumption of residual oxidants in compatible methods
- Sulfitation, bisulfite-addition and reduction reactions specified in synthesis or analysis
- Studies of SO2/bisulfite/sulfite equilibria and pH or temperature effects
- Preparation of quality-control working solutions after assay verification
- Experimental sample treatment when the method specifies sulfurous acid or sulfite under acidic conditions.
