The conversion of hydroxyapatite occurs due to presence of F - ions in water. The correct formula of hydroxyapatite is:
Options
- ACa 3 PO 4 2 · CaF 2
- B3 Ca 3 PO 4 2 · Ca ( OH ) 2
- C3 Ca 3 PO 4 2 · CaF 2
- D3 Ca ( OH ) 2 · CaF 2
Correct answer
B. 3 Ca 3 PO 4 2 · Ca ( OH ) 2
Step-by-step solution
Hydroxyapatite → 3 Ca 3 PO 4 2 · Ca ( OH ) 2 Hydroxyapatite in presence of F - ions converts to fluorapatite 3 Ca 3 PO 4 2 · CaF 2 .
