What is the pH of Hydrofluosilicic acid?
6.5-8.5
At the pH of drinking water (6.5-8.5) and at the concentration usually used for fluoridation (1 mg fluoride/L), the degree of hydrolysis is essentially 100%. Fluorosilicic acid is a moderately strong acid that can corrode glass and stoneware.
What is fluorosilicic acid used for?
Silicofluoric Acid is a fuming, colorless to pale, straw-colored liquid with a sharp, irritating odor. It is used in water fluoridation, metal sterilization, electroplating, animal hide tanning, and glass etching.
Where does fluorosilicic acid come from?
Hydrofluorosilicic acid is a chemical often known by other names like fluorosilicic acid and fluosilicic acid. It’s often abbreviated to HSA or FSA. The acid is a colorless chemical that is created when you take phosphoric rock from the ground and convert it to soluble fertilizer.
Is fluorosilicic acid flammable?
ICSC 1233 – FLUOROSILICIC ACID. Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings, use appropriate extinguishing media.
How do you neutralize fluorosilicic acid?
Lime or calcium hydroxide may be used to neutralize contaminated water and immobilize the fluoride ions as calcium fluoride. Spills of fluorosilicic acid solutions should be diluted with large amounts of water.
What is Hydrofluosilicic acid?
Hydrofluosilicic Acid is also known as F6H2Si, Fluorosilicic Acid, Hexafluorosilicic Acid and Hydrogen Hexafluorosilicate. Hydrofluosilicic Acid is most used in aluminum production and ore refining. Similar to Hydrofluoric Acid, Hydrofluosilicic Acid is a strong corrosive capable of dissolving many storage materials.
What is the difference between Hydrofluorosilicic acid and fluorosilicic acid?
What Is Hydrofluorosilicic Acid? Hydrofluorosilicic acid is a chemical often known by other names like fluorosilicic acid and fluosilicic acid. It’s often abbreviated to HSA or FSA. The acid is a colorless chemical that is created when you take phosphoric rock from the ground and convert it to soluble fertilizer.
What kind of liquid is 23% hydrofluorosilicic acid?
Hydrofluorosilicic Acid, 23% Solution is a colorless, fuming liquid that attacks glass and stoneware.
How does hydrofluorosilicic acid react with metals?
Attacks glass and materials containing silica. Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides). Reacts with active metals, including iron and aluminum to dissolve the metal and liberate hydrogen and/or toxic gases.
