Question

The recommended concentration of fluoride ion in drinking water is up to 1 ppm as fluoride ion is required to make teeth enamel harder by converting $\left[ {3C{a_3}{{\left( {P{O_4}} \right)}_2} \cdot Ca{{\left( {OH} \right)}_2}} \right]\,$ to:

Accepted Answer

$\left[ {3C{a_3}{{\left( {P{O_4}} \right)}_2} \cdot Ca{F_2}} \right]$

Answer

$\left[ {Ca{F_2}} \right]$

Answer

$\left[ {3\left( {Ca{F_2}} \right) \cdot Ca{{\left( {OH} \right)}_2}} \right]$

Answer

$\left[ {3\left\{ {C{a_3}{{\left( {P{O_4}} \right)}_2}} \right\} \cdot Ca{F_2}} \right]$
