Vedclass · Answer

(C) Polyphosphates,such as sodium hexametaphosphate $(Na_6P_6O_{18})$,are commonly used as water softeners. They work by sequestering the metal ions responsible for water hardness,such as $Ca^{2+}$ and $Mg^{2+}$. These ions are $cationic$ in nature. The polyphosphate anions form stable,water-soluble complexes with these $Ca^{2+}$ and $Mg^{2+}$ ions,thereby preventing them from reacting with soap or forming scale. Therefore,they form soluble complexes with cationic components.

Polyphosphates are used to soften water because they:
