Bones are mostly calcium phosphate. Calcium chloride reacts with potassium phosphate to form calcium phosphate and potassium chloride. Indicate the physical states or reactants and products

a) Write the balanced equation of the information above

b) Determine the total ionic equation

  1. DrBob222

    3CaCl2(aq) + 2K3PO4(aq) ==> Ca3(PO4)2(s) + 6KCl(aq)

    You add the phases.
    3Ca^2+ + 6Cl^- + 6K^+ + 2PO4^3- ==> Ca3(PO4)2(s) + 6K^+ + 6Cl^-

    You turn that into a net ionic equation by canceling those items that appear on both sides; i.e., the Cl^- and K^+ to leave you with the net ionic equation of
    3Ca^2+(aq) + 2PO4^3-(aq) ==> Ca3(PO4)2(s)
