Food Grade Baking Soda Sodium Bicarbonate 25kg Bag - 99.0-100% Purity, pH 8.5 Industrial Grade
High-purity food grade sodium bicarbonate (NaHCO₃) with CAS No. 144-55-8, packaged in convenient 25kg bags for industrial and commercial applications.
Manufactured using sodium sulfate (Na₂SO₄) sourced from sodium nitrate tailings and by-product waste from environmental industries including new energy, coal chemical, metallurgical steel, and textile sectors. Produced through double decomposition reaction with ammonium bicarbonate (NH₄HCO₃), yielding by-product fertilizer ammonium sulfate ((NH₄)₂SO₄). Features low chlorine or chlorine-free characteristics to meet specific industry requirements.
