Question

Solubility and Temperature Gizmo

(YOU MUST BE LOGGED INTO CONNEXUS on a separate tab TO ACCESS THE GIZMO)

If the Gizmo does not load, you may need to clear your cache and cookies from your browser. HERE is a video on how to do that.





Watch the video linked HERE to learn how to use the Gizmo to collect your data.





You will also need a calculator for this question, if you do not have a calculator, please use the Desmos calculator linked HERE.



Follow these steps to use the Gizmo to measure the solubility of potassium nitrate at each temperature given in the table below.

Click "BAR CHART" Tab at the top of the Gizmo.
Click "Show Numerical Values" box below the bar chart.
Type temperature in the temperature box. Click "ok."
ADD 10 GRAMS AT A TIME AT EACH TEMPERATURE UNTIL IT SETTLES OUT AT THE BOTTOM (GREEN BAR).
SUBTRACT: ADDED - AT BOTTOM TO GET THE SOLUBILITY AT EACH TEMPERATURE. RECORD EACH AMOUNT (IN GRAMS) IN THE TABLE BELOW. DO NOT ROUND YOUR ANSWERS TO THE NEAREST WHOLE NUMBER!
YOU MUST RESET THE GIZMO EACH TIME AND CHANGE THE TEMPERATURE, THEN PRESS OK.

Answer 1

I'm unable to access external resources, including the Gizmo to gather specific solubility data. However, I can guide you on how to use the Gizmo to perform the experiment and gather your data.

Here’s a step-by-step approach, which you can follow:

1. Access the Gizmo: Ensure you are logged into Connexus and navigate to the “Solubility and Temperature” Gizmo.

2. Set up the Experiment:

   • Click on the "BAR CHART" tab at the top.
   • Check the "Show Numerical Values" box.

3. Enter Temperature: Start with the first temperature (5°C) by entering it into the temperature box and clicking "OK."

4. Add Potassium Nitrate:

   • Begin adding potassium nitrate in increments of 10 grams.
   • Continue adding until you see that the solid starts to settle at the bottom (indicated by the green bar).

5. Measure Solubility:

   • Once you find the maximum amount that can dissolve, note the total grams added.
   • Then, note the grams at the bottom (the amount that didn’t dissolve).
   • Subtract the undissolved amount from the added amount to calculate the solubility.

6. Record Your Data: Write your resulting solubility (the result of the calculation) in the table for that specific temperature.

7. Reset and Repeat: After recording the data, reset the Gizmo and repeat the process for each of the temperatures (15°C, 25°C, etc.) until you complete the table.

This will give you the solubility of potassium nitrate at various temperatures.

If you encounter any issues during the experiment or have specific questions about the process, feel free to ask!
