Explanation:
Detailed explanation-1: -It is a precipitate. One of the goals of this section is to help you to visualize the process described by this equation. Figures 7.10, 7.11, and 7.12 will help you do this. surround the calcium and sodium ions, and the hydrogen ends of water molecules surround the nitrate and carbonate ions.
Detailed explanation-2: -Here, cobalt(II) chloride (CoCl2) is added to sodium carbonate (Na2CO3). The result is a pink precipitate.
Detailed explanation-3: -BaCl2 gives white precipitate with an aqueous solution of a salt.
Detailed explanation-4: -A milky white sodium chloride precipitate forms immediately. In time the solid will precipitate out. Care should be excercised when handling concentrated hydrochloric acid.
