For full credit, be sure to include ion charges and phase labels. The chemical formula of "Product B" in the net ionic equation is: Synthesis of "Product B" 1. Using your graduated cylinder add 50.0 mL of distilled water to the solution (cooled back to approximately room temperature) containing "product A". The total volume of solution at this point should be approximately 75.0 mL. % Once the "air space" above the solution is no longer brownish red colored, you may bring the flask out of the hood and continue working at your normal work area. This typically happens right before or after this step. 2. Measure 30.0 mL of 6.0 M NaOH using a graduated cylinder. If you are using the same graduated cylinder that you used in the synthesis of product A, make sure you rinse it thoroughly with first tap and then distilled water before using it to measure the sodium hydroxide. 3. Slowly and cautiously over the course of 2 - 3 minutes, add the 30.0 mL of 6.0 M NaOH to the blue solution containing "product A". Make sure you continuously swirl the Erlenmeyer during the addition to mix the NAOH solution completely with "product A" and minimize other reactions. 4. Test the solution with red litmus paper to determine if it is basic by putting the tip of your stirring rod in the liquid layer and then touching the tip of the rod to a piece of red litmus paper. A basic solution will turn red litmus paper blue so the point where you touched the paper should be blue. If the solution is basic, proceed to the next step, if it is still acidic, continue to add NAOH in 5.0 mL increments (don't forget to swirl the solution with each addition) until it is basic when tested with litmus paper. 5. The light blue precipitate that forms in this reaction is the copper-containing "product B". 6. Record your observations on your data sheet. (After lab) Then write a balanced net ionic equation for this reaction and answer any related questions. For your balanced equation, note that the reactants are "product A" and sodium hydroxide. Consult your solubility guidelines GKFBD, section 4.7, page 171, for additional guidance regarding the identity of "product B" and writing your net ionic equation.
