To determine the answer for the water conductance lab, you need to measure the conductivity of the different NaCl solutions with various concentrations: 500 ppm, 1,000 ppm, 5,000 ppm, and 10,000 ppm.
Here's how you can approach the lab experiment:
1. Set up the experiment: Prepare four separate containers or beakers for each of the NaCl solutions. Label them accordingly.
2. Measure the solutions: Use a measuring cylinder or pipette to accurately measure the required amount of NaCl for each concentration. Mix distilled water and the measured NaCl to prepare the desired concentration. Make sure to thoroughly dissolve the NaCl in the water.
3. Measure conductivity: Use a conductivity meter or probe to measure the conductivity of each NaCl solution. Ensure that the probe is properly calibrated according to the manufacturer's instructions.
4. Conduct the measurements: Immerse the probe of the conductivity meter into the first NaCl solution (500 ppm). Wait for the reading on the meter to stabilize, and record the conductivity value in units of siemens per meter (S/m) or microsiemens per centimeter (µS/cm).
5. Repeat the process: Repeat step 4 for each of the remaining NaCl solutions, noting down the conductivity readings for 1,000 ppm, 5,000 ppm, and 10,000 ppm of NaCl.
6. Analyze the results: Once you have recorded all the conductivity values, you can compare and interpret the data. Typically, the higher the concentration of NaCl, the higher the conductivity, as more ions are present to facilitate the flow of electric current.
Note: Make sure to follow proper safety protocols during the experiment, including wearing appropriate protective gear and disposing of chemical waste responsibly.
By following these steps and measuring the conductivity of the NaCl solutions at different concentrations, you can obtain the answer to the water conductance lab.
