Correct option is D- treatment with sodium hexametaphosphate -Na-6P-6O-18-The permanent hardness of water can be removed by using Calgon process-Na-2-Na-4-PO-3-6-2Ca-2-Mg-2-rightarrow -underset-text-soluble complex-Na-2-Ca-2-Mg-2-PO-3-6-4Na-

Permanent hardness of water can be removed by:

Correct option is D. treatment with sodium hexametaphosphate $$(Na_6P_6O_{18}$$)
The permanent hardness of water can be removed by using Calgon process.

$$Na_2[Na_4(PO_3)_6]+2Ca^{2+}/Mg^{2+}\rightarrow \underset{\text{soluble complex}}{Na_2[Ca_2/Mg_2(PO_3)_6]}+4Na^+$$
