This solution provides an efficient, ready-to-use liquid source of citric acid, eliminating the operational challenges associated with dissolving dry crystalline powder in industrial workflows. Formulated with high-purity raw materials, this 50% concentration is designed for precise pH control, metal surface treatments, and scale removal across diverse commercial sectors. By procuring pre-diluted solutions, operators reduce manual handling, dust inhalation risks, and batch-to-batch variation, ensuring consistent industrial chemical processing.\u003c\/p\u003e\u003cp\u003eAs a primary organic acid, this solution performs key roles in metal cleaning, agricultural formulations, and industrial water treatment. It acts as an effective chelating agent, binding multi-valent metal ions to prevent precipitation and scaling in piping systems. The liquid format allows for automated dosing and metered integration directly into existing process lines. Alliance Chemical supplies this chemical in various packaging volumes—from 1-quart containers to multiple 1-gallon cases—to accommodate specific operation scales of \u003ca href=\"\/products\/citric-acid-50-solution\"\u003eCitric Acid 50% Solution\u003c\/a\u003e. We maintain rigorous quality control standards in our \u003ca href=\"\/collections\/acids\"\u003eacids collection\u003c\/a\u003e to deliver dependable chemistry for all technical, manufacturing, and industrial applications.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eSelecting a 50% concentration liquid format over dry crystalline forms is critical for maintaining process efficiency and dosing accuracy. At 50% concentration, the solution remains stable under standard operating temperatures without premature crystallization or precipitation out of the liquid phase. Using a pre-formulated liquid minimizes preparation errors that occur during manual dry dissolution, such as local concentration spikes or incomplete dissolving of granules. This concentration offers the optimal balance between high active acid content and manageable viscosity, making it highly compatible with standard industrial metering pumps and automated injection systems.\u003c\/p\u003e\u003cp\u003eChoosing an incorrect concentration or lower grade can lead to severe system failure modes. Inadequate concentration control can cause incomplete neutralization reactions, resulting in out-of-spec pH levels in wastewater discharge systems. Undissolved particulates from poorly dissolved powder can clog fine spray nozzles, ruin expensive membrane filters, and cause premature wear on pump impellers. Furthermore, using unverified technical grades with excessive trace metal impurities can catalyze unwanted side reactions in chemical syntheses or cause corrosion on sensitive metal surfaces instead of targeted passivation.\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\u003e77-92-9\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eC6H8O7\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e192.12 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003eDecomposes (NTP, 1992) °C\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e307 °F (anhydrous) (NTP, 1992)\u003c\/dd\u003e\n\u003cdt\u003eFlash Point\u003c\/dt\u003e\n\u003cdd\u003e100 °C\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.54 at 68 °F (USCG, 1999) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eCitric acid appears as colorless, odorless crystals with an acid taste.
