1. CHEMISTRY JANUARY 12, 2015 LAB 09 – PART 1

2. PRE-LAB TURN ON COMPUTER TAKE THE PAPER AND ANSWER THE PRE-LAB QUESTION – CAN SALTWATER BE UTILIZED TO POWER A LIGHT BULB?

3. AIM CAN SALTWATER BE UTILIZED TO POWER A LIGHT BULB?

4. PHET SIMULATION GO TO LABS (link on the left side) Click on the Labs folder Scroll to the bottom and choose Lab 09 – Ionic/Covalent Today we are working on the Macro Tab lab portion

5. PHET SIMULATION Click on the PHET Simulation to launch it Follow the instruction to launch the simulation

6. PURE WATER In this lab we are looking at conductivity. First we will see if water alone is able to conduct electricity. Do steps 1 and 2 and record your observations.

7. SALT Now let’s see what happen when you add salt to water. Do step 4 and record your observation and answer the question. This should take about 5 minutes.

8. SUGAR RESET THE SIMULATION NOW, GO TO STEP 5-6 AND PERFORM THE STEPS BY ADDING SUGAR TO THE MIX. WHAT HAPPENS?

9. POST LAB What is the bond that exists in salt (NaCl)? What is the bond that exists in sugar (C 12 H 22 O 11 ? Does ionic compound conduct electricity? Does covalent compound conduct electricity?

10. AIM PROMPT RESPOND TO THE FOLLOWING: – AIM Prompt: Can saltwater be utilized to conduct electricity? Respond in paragraph form and make sure to use the RACE format.
