Write Lewis structures for the following ionic compounds: (a) calcium chloride; (b) barium sulfide; (c) lithium oxide; (d) sodium fluoride.
1 1. Deionized water- water that has had all the natural ions in it removed 2. The indicator to be used in the titration experiment will be calmagite. The color should be reddish and eventually turn to a pemamanent blue color which indicates it has reached its equivalence point. 3. Inside a water softener, is filled with small polystyrene beads, which carry a negative charge. When the water enters this area of the tank, the positive ions such as magnesium or calcium in water cling to the beads. The attraction to the beads is stronger than that of the polar attraction to the H 2 molecules. This leaves the water free of unwanted minerals. Eventually, the beads become overwhelmed by ions and a regeneration or flushing of the tank i
