In the world of industrial chemicals, sodium_sulfite plays a vital role. It supports several sectors, from food and water treatment to textiles and photography. At Basekim, we proudly supply high-purity sodium_sulfite anhydrous that meets global quality standards. Let’s dive into its properties, benefits, and uses so you can choose the right product with confidence.
Simply put, sodium_sulfite is a white, water-soluble powder. Chemically, its formula is Na₂SO₃, and it contains sodium, sulfur, and oxygen. Importantly, sodium sulfite pH in a 10% solution ranges around 9–10, which shows it is mildly alkaline.
Moreover, sodium sulfite melting point is about 33.4°C for the pentahydrate form and higher for sodium sulfite anhydrous. Because of this low melting point, it performs well in both hot and cold processes.

ToggleNow, let’s look at some key Na₂SO₃ uses:
In water treatment, it removes excess chlorine and protects equipment.
In the paper industry, it works as a pulping chemical.
In textile dyeing, it acts as a bleaching and reducing agent.
In photography, it prevents oxidation of developer solutions.
In food, sodium sulfite in food functions as a preservative (though regulated in many countries).
Clearly, its versatility supports many industries. Therefore, many buyers regularly source it from experienced suppliers like Basekim.
