The Science behind pH
pH indicators are incredibly useful tools in science; they help us determine where a substance sits on the acid-to-alkaline spectrum. In this video, a STEM expert at Robert Gordon University’s School of Pharmacy and Life Sciences shows us how we can make our very own pH indicator and use it on various substances found at home.
Using a Homemade pH Indicator
Follow our Expert Guidance
Once you have your own homemade pH indicator (easily obtained by boiling some red cabbage and collecting the water), you can repeat this experiment at home. We recommend using the accompanying guidance to help you safely determine the pH of other household substances available to you.Download Guidance
