Manganese Sulphite – 500 gram Packs

Manganese Sulphite is an inorganic salt formed from manganese(II) and sulphite ions, with the ideal anhydrous composition MnSO3. It differs chemically from manganese sulphate because sulphite contains sulphur in a lower oxidation state and can participate in oxidation and acid-base processes. The solid is used mainly in investigations of inorganic sulphur chemistry and manganese-containing compounds rather than as a general-purpose soluble reagent. Exposure to strong acids may liberate sulphur dioxide, and the sulphite ion can be oxidized to sulphate. These properties make manganese sulphite an instructive substance for specialized laboratory discussions of redox chemistry and salt stability. Any hydrated form must be identified separately before calculating molar quantities or using a form-specific specification. This listing is for the 500 gram pack size.

Choose the reagent only when the verified form and laboratory safety controls match the intended application.

Frequently Asked Questions About Manganese Sulphite

How is manganese sulphite different from manganese sulphate?

Manganese sulphite is represented by MnSO3, while manganese sulphate is MnSO4. The distinction is an oxygen atom in the anion and a different oxidation state of sulphur. Their chemical stability and redox behaviour differ, so substituting one reagent for the other would alter an experiment.

What is the CAS number of manganese(II) sulphite?

The anhydrous manganese(II) sulphite entry is listed as CAS 13568-71-3, with a formula mass of approximately 135.00 g/mol. Since a commercial product may have a specified hydration state, confirm its identity before using the figure for quantitative calculations.

Can manganese sulphite release a gas with acids?

Acidification of sulphite salts can generate sulphur dioxide, a respiratory irritant. Reaction trials should be limited to suitably equipped and supervised laboratories with an appropriate risk assessment and ventilation. Never mix unknown sulphite residues into acidic waste containers.

Why might manganese sulphite change during storage?

Sulphites can undergo oxidation to sulphates when exposed to oxidizing conditions. Moisture and contamination may also influence the solid’s behaviour. Maintain a closed, dry container and verify the material condition when experimental accuracy requires a defined composition.

Is manganese sulphite appropriate for routine school experiments?

It is not automatically appropriate for unsupervised school practicals. Any educational use should be chosen by a qualified instructor after reviewing the Safety Data Sheet, considering sulphur dioxide release and manganese exposure, and ensuring suitable ventilation and waste collection.

Storage Conditions for Manganese Sulphite

Store manganese sulphite in a tightly closed container protected from moisture, air contamination and strong oxidizing agents. Keep it separate from acids because acidification can evolve sulphur dioxide. Use an appropriately ventilated, cool and dry laboratory storage space. Maintain a clear identity label and avoid repeated opening when the intended experiment requires a chemically defined sulphite composition.

Precautions for Handling Manganese Sulphite

Read the current Safety Data Sheet before using manganese sulphite. Wear gloves, protective eyewear and a laboratory coat, and control the formation of airborne powder. Avoid contact with acids and oxidizing agents unless a supervised experiment with effective ventilation has been approved. Sulphur dioxide may be produced under acidic conditions; manage spills and sulphite-containing waste according to established laboratory procedures.
