pH again
You can use the same kind of logic on pH. Here are two problems
The pH of lemon juice is 4.2. The pH of milk is 7.8. What is the difference in hydrogen ion concentration (approximately)?
Finally, can figure out how to use the "unlogging" trick to calculate the concentration?
The pH of lemon juice is 4.2. How many moles of H+ are present in 5 L of lemon juice?
