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).
Is sodium hexametaphosphate safe for dogs?
Generally yes—it's commonly used in dog foods and dental chews to help reduce tartar and is considered safe at approved levels; dogs with kidney disease or on phosphorus-restricted diets should avoid excess phosphates and you should consult your vet.
Is sodium hexametaphosphate safe?
Yes—it's permitted as a food additive (EU E452i) and considered safe at typical use levels; EFSA set a group ADI for phosphates of 40 mg/kg body weight per day expressed as phosphorus.
Is sodium hexametaphosphate bad for you?
Not at normal food levels; however, very high phosphate intake can disrupt mineral balance and is a concern for people with kidney disease.
Is sodium hexametaphosphate safe in food?
Yes—it's an approved emulsifier/sequestrant (E452i) and is safe within permitted levels; authorities limit total phosphate intake (e.g., EFSA ADI 40 mg/kg bw/day as phosphorus).
What is sodium hexametaphosphate used for?
In foods it functions as a sequestrant, emulsifier, stabiliser, humectant and thickener—binding metal ions, stabilising proteins/emulsions, and retaining moisture in products like processed meats/seafood, cheeses/dairy, beverages, and baked goods.
