Why Citric Acid 50% Solution
Citric Acid 50% Solution (CAS: 77-92-9) provides a concentrated, pre-dissolved organic acid that eliminates the time-consuming and dust-producing steps of mixing solid powders. With the chemical formula C6H8O7, this Reagent grade liquid delivers the precise chemical consistency and purity required for exacting analytical laboratory methods and stringent manufacturing processes. The transparent, pale, and slightly viscous solution offers substantial acidic strength while maintaining predictable flow characteristics. This allows facility operators to inject the chemical directly into automated dosing systems. Furthermore, it presents a stable operational profile with a flash point of 230 degrees Fahrenheit, ensuring reliable performance across industrial and analytical environments requiring complete water miscibility.
Best Applications for This Grade
-
Precision Analytical Chemistry: Commonly applied in rigorous laboratory environments where a Reagent grade chemical is necessary. It serves effectively to prepare standardized buffer solutions, execute quantitative titrations, and facilitate complex analytical separations without introducing trace metal impurities into the data.
-
Metal Passivation and Surface Finishing: Commonly applied in metalworking facilities to chelate metal ions and strip oxides from machined surfaces. The 50% concentration provides an aggressive, highly controllable liquid etching medium that rinses away completely due to its complete water miscibility, leaving bare metal prepared for subsequent processing.
-
Automated Water Treatment Dosing: Commonly applied in wastewater management facilities requiring strict pH reduction and alkalinity control. The concentrated liquid form allows for immediate dispersion and reaction in moving water streams, completely avoiding the dissolving lag times inherent to solid crystalline chemicals.
-
Industrial Chelating Operations: Commonly applied in heavy industrial descaling and system cleaning. The Reagent grade formulation acts as a targeted chelating agent to bind dissolved calcium and magnesium ions, effectively preventing scale formation inside critical heat exchangers and boilers without resorting to harsher mineral acids.
When to Choose a Different Grade
- If facility requirements dictate a pre-diluted, less concentrated liquid to prevent over-acidification during sensitive batch processing or lighter environmental water treatments, select Citric Acid 25% Solution.
- If the specific operational protocol demands a dry, powdered formulation rather than a liquid solution to eliminate excess water weight and control moisture content during dry chemical blending, select Citric Acid Monohydrate - USP Food Grade.
- If regulatory compliance mandates an ingredient authorized for human consumption, food processing, dietary supplements, or beverage acidulation, you must step off the Reagent tier and select Citric Acid Monohydrate - USP Food Grade.
