Which polyphosphate is commonly used in detergents? Give a balanced chemical equation for the hydrolysis of it

Question

Which polyphosphate is commonly used in detergents and write a balanced chemical equation for the hydrolysis of this polyphosphate? =)

Answer 1

Sodium tri-polyphosphate (Na5P3O10) has been used widely as a constituent of laundry detergents, but there are others. Upon hydrolysis, various Sodium Hydrogen Phosphates are produced.

Na5P3O10 + 2 H2O --> NaH2PO4 + 2 Na2HPO4

The products are both called ortho phosphates. The first is Sodium dihydrogen phosphate and the other is Disodium hydrogen phosphate.
