This product, also known as liquid caustic soda, features the molecular formula HNaO and has a molecular weight of 39.997 g\/mol — critical properties for standard chemical formulation calculations. Our 25% concentration offers a stable, pre-diluted format that minimizes the safety hazards and exothermic risks associated with dissolving solid sodium hydroxide flakes or beads on-site. It serves as a vital pH regulator, reactant, and processing aid across numerous manufacturing sectors.\u003c\/p\u003e\u003cp\u003eWith a CAS number of 1310-73-2, this colorless and odorless liquid is more dense than water, with a density of 1.5 at 68 °F (USCG, 1999). It is highly soluble in water and exhibits a strongly alkaline pH even in highly diluted solutions. Alliance Chemical distributes this versatile base across our \u003ca href=\"\/collections\/bases\"\u003eBases collection\u003c\/a\u003e in various packaging configurations, from single quarts to multi-gallon cases, ensuring that your facility receives the exact volume required for seamless operations. This chemical is corrosive to metals and tissues, requiring strict adherence to standard industrial handling protocols.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eSelecting a 25% concentration of sodium hydroxide is critical for processes where precision pH adjustment and chemical reaction rates must be tightly controlled. This specific concentration prevents the severe crystallization and freezing issues common with higher concentration solutions (such as 50% caustic soda) in colder climates, while still providing sufficient chemical strength for heavy-duty applications. For facilities without specialized dilution equipment, utilizing a pre-formulated 25% solution eliminates operational variability and ensures consistent batch quality.\u003c\/p\u003e\u003cp\u003eUtilizing the incorrect concentration or an uncertified grade can lead to catastrophic process failures, such as localized overheating from unexpected exothermic dilution, rapid equipment corrosion, or unwanted precipitation in process piping. In municipal and industrial wastewater systems, using an inconsistent concentration can disrupt the delicate chemical balance, leading to discharge permit violations. By sourcing this standard 25% solution, operators can guarantee predictable neutralization curves and avoid the structural damage associated with runaway alkaline reactions.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e1310-73-2\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eHNaO\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e39.997 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003egreater than 266 °F at 760 mmHg (USCG, 1999)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e604 °F (USCG, 1999)\u003c\/dd\u003e\n\u003cdt\u003eFlash Point\u003c\/dt\u003e\n\u003cdd\u003eN\/A °C\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.5 at 68 °F (USCG, 1999) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eSodium hydroxide solution appears as a colorless liquid.
