O a) Sodium lon
Ob) Aluminium lon
c) Potassium Ion
O d) Hydrogen lon​

Answer 1

Answer:

Permutit or zeolites are packed in a suitable container and a slow stream of hard water is passed through this material. As a result, calcium and magnesium ions present in hard water are exchanged with sodium ions in the permutit (Na+Al-Silicate). The outgoing water contains sodium salts, which do not cause hardness. 

CaCl2+2Na+→Ca(Al−silicate)2+2NaCl

MgCl2+2Na+→Ca(Al−silicate)2+2MgCl 

So here the sodium ions are exchanged with both  Ca2+ and Mg2+ ions.

Hence options B & D are correct.
