pH Scale
We tried to explore the concept of acidity and basicity along with how to measure it quantitatively using the Phet simulation.

Reflection
- The acidic or basic nature of some common solutions: Water, Battery acid, Chicken Soup, Blood, Coffee, Drain Cleaner, Milk, Hand Soap, Orange Juice, Soda Pop, Spit, Vomit.
- How the pH scale and it values can be used to determine the acidic or basic nature of a solution?
- Suppose we take a basic solution and started diluting it. What will the pH of the solution at infinite dilution?
Note: We performed the experiment using the simulation and got the below curve. It can be used as a hint to guess the answer. Also is there any alternative logic to obtain the same answer?
- How to define pH?
- Relationship between pH and pOH.
- There is no relationship between pH of a solution and it’s color.
- Determination of concentration and number of H^+ and OH^- ions in the solution from the pH of the solution.
