I need help, I don't understand this at all! I want to use Orange Juice. So what do I do?
Find the hydrogen ion content of a substance of your choice.
Using this hydrogen ion content, show how to find the pH of the substance using the formula. Is this substance acidic or basic? Why?
Round the pH to three decimal places.
Try the easy case of pure water.
[H+]*[OH-] = 1.00*10^-14
[H+] = [OH-] since there are no other ions present
Solve for [H] and use the definition of pH
For other compounds, you will have to use additional dissociation or equilibrium constants to get the pH
