The concentration of fluroide ions in drinking water upto 1 ppm make the enamel on teeth much harder by converting `ul(x)` into fluorapatite. What is `ul(x)`?

Options

A. `[3Ca_(3)(PO_(4))_(2)*CaF_(2)]`
B. `[3Ca_(2)(PO_(4))_(2)*Ca(OH)_(2)]`
C. `[3Ca(OH)_(2)*Ca_(3)(PO_(4))_(2)]`
D. `[Ca_(3)(PO_(4))_(2)*3CaF_(2)]`

Answer

B

Explanation

Fluoride is a chemical element that is found most frequently in ground water. Fluoride has a great affinity for the developing enamel because teeth apatite crystals have the capacity to bind and integrate fluride ion into the crystal lattice. The concentration of fluoride ions in drinking water upto 1 ppm make the enamel on teeth much harder by converting `[3Ca_(3)(PO_(4))_(2)*Ca(OH)_(2)]` into fluorapatite `[3Ca_(3)(PO_(4))_(2)*CaF_(2)]`.
`underset((X))([3Ca_(3)(PO_(4))_(2)*Ca(OH)_(2)]) underset(1" ppm")overset(F^(-))(rarr)underset(("Fluorapatite"))([3Ca_(3)(PO_(4))_(2)*CaF_(2)])`
