But there are also a lot I do not know. So perhaps it would be a good idea to start a collection of pH values based on contributions from the students. I could equip them with pH paper (standardize the method) and have them spend a half day going around measuring the pH of anything that catches their curiosity.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It occurred to me that I don&#8217;t have a good idea what the pH of certain things are.
