Steps:

1. Hover over the instruments to understand their functions, then click Start to begin the experiment.
   
2. Choose one of the following options:
   • Standardize Your HCl Solution → Click Standardization of HCl
   • Directly Jump to Main Experiment → Click Main Experiment
   
   

Standardization of HCl:
3. Click on the flask to pour 5 ml Na₂CO₃ into the measuring cylinder.
4. Click on the measuring cylinder to transfer 5 ml Na₂CO₃ into the conical flask.
5. Click on the micropipette to collect 3 drops of Bromo Cresol Green indicator.
6. Click again on the micropipette to add the indicator to the flask.
7. Click on the flask to start titration.
8. Shake the flask and add HCl drop by drop until the solution changes from blue to yellow.
9. Click Next to proceed to the main experiment.

Main Experiment:
10. Click on the borax powder plate to add 25 g of borax into the flask.
11. Click on the water beaker to pour 75 ml distilled water.
12. Click on the measuring cylinder to transfer that 75 ml distilled water into the flask.
13. Click on the flask to mix the solution for 10–15 minutes.
14. Place the flask in the temperature bath, set the required temperature, and wait 10 minutes.
15. Collect 5 ml borax solution using the micropipette and pour it into fresh and clean flask.
16. Add Bromo Cresol Green indicator using the micropipette.
17. Click on the flask to start titration.
18. Shake the flask and add standard HCl until the solution turns yellow.
19. Repeat the experiment for other temperatures, starting again from Step 10.
