N factor of calcium phosphate Ca3(PO4)2 is
6NaCl + Ca3(PO4)2 --(gives)--2Na3(PO4) + 3CaCl2
To get two mole of Na3(PO4)2, 6 moles of NaCl are consumed, which means 6 Na + ions are consumed. Thus, 6 moles of Na+ ions are consumed by 3 moles of Ca2+ ions . So, Each mole of Calcium phosphate replaces 3 mples of cationic charge. So, the N factor of calcium phosphate is 3.
