Question

State True or False.

The molecular formula of tricalcium phosphate is $C{a}_3{\left(P{O}_4\right)}_2$.

• A. True
• B. False

Answer 1

The correct option is A True

The molecular formula of tricalcium phosphate is $C{a}_3{\left(P{O}_4\right)}_2$. It contains 3 calcium ions (each having charge +2) and 2 phosphate ions (each having charge +3). Total positive charge on cations $=+6$.
Total negative charge on the anions $=2(-3)=-6$ . Thus, total positive charge on cations is balanced with total negative charge on anions and the electrical neutrality is maintained. Hence, the molecular formula is correct and the given statement is correct.
