Open this simulation and click the Macro tab. The simulation allows you to check the pH scale of various liquid solutions. To get started, go to the drop-down menu at the top of the page and select a liquid from the list. Use the
dropper below the drop-down menu to add the liquid to the container. You can change the concentration of the solution
by adding water using the tap I really need help. on the right. You can also drain the solution using the tap near the left of the container, At
any point, check the pH scale of the solution by dragging the green scope to the container, Try checking the pH level of
different solutions, and then answer the following questions,

Part A
What information does this computer model provide?

Part B
What values or parameters can you adjust in this computer model?

Part C
What benefits does using this model have over performing the modeled procedure with physical materials?

Part D
What benefits does performing this investigation in the physical world have over the computer simulation?

Part E
Imagine that you are using a similar computer simulation to conduct an experiment on the pH value of different liquid
hand soap solutions and water. What is a potential source for error in such a computer model?
