Popular questions
How many formula units of magnesium phosphate will be produced from 35.8 g of sodium triphosphate?
You can’t determine that from 35.8 g of pentasodium triphosphate alone—you need a balanced reaction and the amount of Mg2+ present, and in practice STPP mainly chelates magnesium rather than precipitating Mg3(PO4)2 unless it hydrolyzes to orthophosphate under specific conditions.
How much sodium triphosphate in dish soap?
Most household dishwashing liquids (and many automatic dishwasher detergents) now contain 0% phosphate due to regulations; some industrial/ institutional formulations can still include up to several–tens of percent STPP—check the product label or safety data sheet.
What chemistry experiment to do with sodium triphosphate?
Demonstrate water softening by comparing soap lather or measuring water hardness (EDTA titration) before and after adding a small, known amount of STPP to hard water.
What is pentasodium triphosphate toothpaste?
A toothpaste that includes pentasodium triphosphate (STPP) as a tartar‑control/whitening agent, binding calcium to reduce calculus and help lift surface stains; it’s used at low, safe levels for oral care.
What is pentasodium triphosphate used for?
As a food additive (E451i) it acts as a sequestrant, emulsifier and stabiliser to retain moisture and improve texture in processed meats/seafood and to control metal ions; outside food it’s widely used as a detergent builder and water softener, with an EFSA group ADI for phosphates of 40 mg/kg bw/day (as phosphorus).
What is the refractive index of ktpp?
There isn’t a single published refractive index for solid pentapotassium triphosphate; food-grade specs don’t list it. For aqueous solutions, refractive index depends on concentration and temperature, so you’d need to measure nD under your specific conditions.
What is the refractive index of potassium triphosphate?
A fixed refractive index isn’t typically reported for the solid; it’s not a standard QC parameter for this additive. In solution, the refractive index increases with concentration and varies with temperature and wavelength, so measure it for your formulation.
What is the refractive index of potassium tripolyphosphate?
No standard single value is published for the solid; specifications for E451ii don’t include refractive index. For practical purposes, determine nD on your specific potassium tripolyphosphate solution at the required concentration and temperature.
