Chloride and Sodium Carbonate Reaction - Chemistry Assignment Help

Assignment Task

Place each solid in a separate beaker and add 25–30 mL of distilled water to each beaker. Gently stir the mixtures to dissolve the salts. Use a different stirring rod for each beaker to avoid cross–contaminating the solutions.

2. Record the color of each solution in Table 1.

3. Slowly add a little CuCl 2 solution to the Na 2 CO 3 . Swirl to mix. Record your observations in Table 1.

4. Continue to slowly add the CuCl 2 to the Na 2 CO 3 and swirl to mix. The continuous, slow addition of CuCl 2 along with swirling allows the greatest number of reactant ions to contact each other. The result is a greater amount of products formed.

5. When all of the solution is added, rinse the empty beaker with 3–5 mL of distilled water and add the rinse water to the mixture.

6. Obtain a piece of filter paper. Fold it in half and then in half again as shown. Write your name in pencil near the top outside edge of the filter paper.

7. Measure and record the mass of the filter paper in Table 2 on your answer sheet.

8. Place the filter paper in the funnel, and set the funnel inside the iron ring to suspend it above the empty flask as shown. Allow the funnel to enter the neck of the flask.
