Calcium Fluoride Determine the number of calcium ions per unit cell. Determine the number of fluoride ions per unit cell. What is the empirical formula of calcium fluoride based on the relative number of each ion in the unit cells? Is the empirical formula determined from the lattice structure in agreement with the one predicted by the typical ion charges? Are the anions or cations arranged in one of the basic cubic unit cells (simple, body-centered, face-centered)?
Write the symbols, with charges, for ions formed by calcium, magnesium, strontium, potassium, and sodium, as well as the ions chloride and nitride. Write formulas and names for the compounds you can make by pairing each of the cations with each of the anions. I will show you what I have so far. I just didn't know how to do cations and anions. I tried anions but don't know if they are right and maybe it needs to be a...

Hard water often contains dissolved calcium ion and magnesium ions. One way to soften water is to add phosphate salts. The phosphate ion forms insoluble precipitates with calcium and magnesium ions, removing them from solution. Suppose that a solution is 5.5×10−2 M in calcium chloride and 9.5×10−2 M in magnesium nitrate. What mass of sodium phosphate would have to be added to 11.5 L of this solution to completely eliminate the hard water ions? (Assume complete reaction.)
