WebFeb 10, 2024 · Soil pH varies from around 3.5 (very acidic) to 8.5 (alkaline). A reading of 7.0 is neutral. A reading of less than 7.0 is considered acidic. If you discover you have a more neutral or slightly acidic result when you do the test it's good news, as amending the soil to make it more acidic is much easier than if you have a very alkaline soil. http://chemistry.elmhurst.edu/vchembook/184ph.html easy smf forum hosting

WebDoing the math, we find that the pK a of acetic acid is 4.8. The use of pK a values allows us to express the acidity of common compounds and functional groups on a numerical scale of about –10 (very strong acid) to 50 (not acidic at all). Table 5.2. 1 at the end of the text lists exact or approximate pK a values for different types of protons ... WebHere’s a quick breakdown of pH levels in soil: pH 3 and under: Very strong acidity. pH 4 to 5: Strong acidity. pH 5 to 6: Moderate acidity. pH 6 to 7: Slight to neutral acidity. pH 7 to 8 ... WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14.
