Potassium Tripolyphosphate Solution
Molecular Formula:K₅P₃O₁₀
Molecular Weight:448.35
Standard:FCC--1999
Grade:Industrial Grade、Food Grade
Note on measuring chelating ability: Weigh out 2.000 g of 50% potassium tripolyphosphate solution and add distilled water to prepare 100 ml of 1% solution. Titrate the prepared 100 ml solution with 1% calcium nitrate solution. Stir until the white precipitate cannot be completely chelated. Record the volume of 1% calcium nitrate used in titration. This volume in mL is the index of chelating ability of potassium tripolyphosphate.

Product Characteristics: It has excellent chelating ability and can form stable chelates with Ca²⁺ and Mg²⁺ in hard water so as to soften hard water, increase cleaning ability, and remove dirt. The white precipitate formed from adding 13 ml(min) of 1% calcium nitrate solution into 100 ml of 1% potassium pyrophosphate solution can be rapidly chelated to produce clear solution. It can form a protective film on the surface of iron, lead, zine, and other metals so as to prevent surface corroding. P₃O₁₀^5- has a strong dispersion ability to disperse finely distributed solid particles so that these fine and trace materials can mix evenly. It has stable pH buffering ability and keep solution pH value unchanged for a long time.

Major Application: It is widely used for surface treatment, paint and coating, detergent, boiler antiscaling, food additive, oil well drilling, textile dye printing ancillary, and others.
