Specific solutions for typical problems when measuring nonaqueous solutionsWith the wide range of organic constituents of solutions that require a pH measurement,there are several techniques that can be used to understand and overcome the problems of measuring nonaqueous solutions.pH and Water - USGS·In a nutshell,the pH level of your soil is how acidic or non-acidic it is.In chemistry terms,high pH means high alkaline,also known as basic (the opposite of acid),while a low pH level means the substance is acidic.Citric acid,for example,has a pH level of roughly 2.2.This explains why you pucker when you drink lemon juice.
