Molecular, Ionic and Net Ionic Equations 1. Strontium compounds are often used in flares because their flame color is bright red. One industrial process to produce low-solubility strontium compounds (that are less affected by getting wet) involves the reaction of aqueous solutions of strontium nitrate and sodium carbonate. Write the balanced molecular equation, the total ionic equation, and the net ionic equation for this reaction. 2. Placing aluminum foil in any solution containing aqueous copper (II) ions will result in a reaction. The reaction is slow to begin with, and then proceeds rapidly. a. Referring to a solubility table, name at least four ionic compounds that could be dissolved in water to make a solution containing aqueous copper (II) ions. b. Write a balanced chemical equation for the reaction of aluminum with one of the compounds you suggested in a). c. Write the total ionic equation for the reactions. d. Write the total net ionic equation for the reactions. 3. One industrial method of producing bromine is to react seawater, containing a low concentration of sodium bromide, with chlorine gas. The chlorine gas is bubbled through the seawater in a specially designed vessel. Write the net ionic equation for this reaction. 4. In hard-water analyses, sodium oxalate solution reacts with calcium hydrogen carbonate (in the hard water) to precipitate a calcium compound. Write the net ionic equation for this reaction. 5. In a laboratory test of the metal activity series, a student places a strip of lead metal into aqueous silver nitrate. Write the net ionic equation for this reaction. 6. Some natural waters contain iron ions that affect the taste of the water and cause rust stains. Aeration converts any iron (II) ions into iron (III) ions. A basic solution (contains hydroxide ions) is added
