Hon Chemistry 5-16-17 pH & Indicators

HON CHEMISTRY – Who knew – chemistry and art!! Great work using pH with electrolysis today!

How are you doing on calculating pH? Acids mean H30+ ions and pH, bases mean OH- ions and pOH. Get the pH of an acid straight from the concentration of the acid. Get the pH of a base by first finding the pOH straight from the concentration of the base and then subtracting that from 14. No problem!! So how do you think someone would use pH?

Don’t forget about learning those indicator colors I told you about. Can you think of anything else that might be a natural indicator? What about tea? Have you noticed how it changes to a lighter shade when you add lemon?
