3) Use a strip of litmus paper to test the pH of the NaOH and record it here:___________. 4) Prepare a cold water bath for the reaction you are about to create. Use a 400mL beaker and fill it about halfway with cold water (you will share this beaker with your lab table). 5) Place your 200mL beaker inside of the 400mL beaker so that the smaller one is surrounded by the cold water. Carefully pour the sodium hydroxide into the copper II nitrate in your 200mL beaker, VERY SLOWLY! Use the stirring rod to mix as you add the NaOH. Record observations of this reaction in the box. • Cu(NO 3) 2: Observations before reaction Observations during and after the reaction • During reaction: • NaOH: • After reaction: 6) Keep stirring until all of the NaOH has been added. Use another strip of litmus paper to test the pH of the resulting solution. If the pH does not match that of the original NaOH, add more NaOH until the colors of the pH papers match. D. What evidence of chemical change did you observe? ________________________________________________ ____________________________________________________________________________________________ E. Was the reaction an exothermic or endothermic reaction? Describe your answer: ___________________________ ____________________________________________________________________________________________ F. The reaction you completed is described below. Write it in symbols: The combination of copper (II) nitrate and sodium hydroxide yield copper (II) hydroxide and sodium nitrate. G. Now circle the reactants, and put a square around the products. Remember to label each reactant and product as (s), (l), (g), or (aq). For the next reaction you will work with an open flame. Collect your hair and any dangling jewelry and never leave the flame unattended. 7) Add 100mL of distilled water to your 200mL beaker and stir. 8) Adjust your ring stand so that the ring is about half foot off of the lab table. Make sure the ring is secure and place your beaker on it. Place a Bunsen burner underneath the ring stand and carefully light it. Stir the contents of your beaker as you are heating it. Remove the beaker when no further color change is occurring. Record your observations.

Write it in symbols: The warming up of copper (II) hydroxide yields copper (II) oxide and water. J. Now circle the reactants, and put a square around the products. Remember to label each reactant and product as (s), (l), (g), or (aq). 9) Gently tip the beaker to pour off the liquid and use the stirring rod to guide the liquid to a beaker below (this is called decanting). Do not remove any of the solid! K. What do you think is the purpose of decanting? _______________________________________________________ _____________________________________________________________________________________________ L. The reaction you completed is described below. Write it in symbols: The warming up of copper (II) hydroxide yields copper (II) oxide and water.
