Soda Ash, Dense
CAS 497-19-8 · Part MC-SODASH · Technical, 99.2%
Dense sodium carbonate in bags and supersacks. A gentler alkali than caustic for pH adjustment where buffering is wanted rather than a hard swing.
Specification
- CAS number
- 497-19-8
- Part number
- MC-SODASH
- Grade
- Technical, 99.2%
- Physical form
- Solid / granular
- Category
- Dry Chemicals
- Also known as
- sodium carbonate, washing soda, dense ash, Na2CO3
Dense grade sodium carbonate, 99.2% minimum. The dense grade flows and handles better than light ash and is what most industrial users want.
Typical uses
- pH adjustment and alkalinity control in water and wastewater — it buffers, where caustic simply raises
- Builder in powdered detergent and cleaner formulations
- Neutralising acidic waste streams without overshooting
- Precipitating hardness and heavy metals in treatment systems
Why choose it over caustic
Soda ash gives a slower, more forgiving pH rise. In a system where an operator is dosing manually, or where overshoot causes a downstream problem, that forgiveness is worth more than caustic’s efficiency. It is also considerably safer to handle.
Store dry and sealed — it cakes when it takes up moisture.

Read the sheet before the first use
Section 2 covers the hazards, Section 8 the protective equipment actually required, and Section 10 what this must not be stored next to. Storage incompatibility is the single most common cause of serious chemical incidents.
