Nature and Use:

A typical strong base and weak acid of anhydrous sodium carbonate. The aqueous solution is alkaline, with a PH value of 11.6 and irritant.

The appearance is white powder or fine particle with no odor and hygroscopic property. 1mol/L of water will be gradually absorbed in the dew air(About 15%). Soluble in water and glycerin, insoluble in alcohol.

It can react with most protic acids (acid stronger than carbonic acid), producing carbon dioxide when the acid is in excess and carbonic acid when it is not excess.

Anhydrous sodium carbonate is used as a reference substance in conventional laboratory quantitative analysis for the determination of aluminum, sulfur, copper, lead and zinc in acid solution.

In the biological domain, high purity grades are used as buffer components for the removal of membrane proteins.

It can also be used in optical glass manufacturing, picture tube glass shell manufacturing.

It is used in pharmaceutical industry as an acidolysis drug and permeable laxative.

Anhydrous sodium carbonate for chemical and electrochemical oil removal, electroless copper plating, etching of aluminum, electrolytic polishing of aluminum and alloy,

Chemical oxidation of aluminum, closure after phosphating, anti-rust between processes, electrolytic removal of chromium coating and removal of chromium oxide film, etc

Used in pre-copper, steel and steel alloy electrolyte.

Packing: 25KG drum or bag, dry and airtight storage.
