The chemical formula for strontium phosphate is Sr3(PO4)2.
Strontium phosphate is an inorganic compound made up of strontium and phosphate ions. In the formula, the Sr represents strontium, which has a +2 charge, and the (PO4) represents the phosphate ion, which has a -3 charge. Since there are three strontium ions needed to balance the charge of two phosphate ions, the overall formula can be derived by ensuring the charges are balanced. Therefore, the strontium phosphate formula is balanced as Sr3(PO4)2.
