Question
Polyphosphates are used as water softening agents because they :
Options
A.form soluble complexs with anionic species
B.precipitate anionic species
C.form soluble complexes with cationic species
D.precipitate cationic species
Solution
Na2[Na4(PO3)6] + Ca2+ → Na2[CaNa2(PO3)6] + 2Na+
Sodium polyhexa Solube Complex salt
meta phosphates
Because sodium podium polyhexa metaphosphates form soluble complexes with ions responsible for hardnening (e.g., 2Na+) of water.
