The ph scales
WebbThe pH scale is considered a logarithmic scale corresponding to the concentration of protons (H+ ions) in aqueous solutions. So, pH is the negative log of [H+] and can be calculated using the following formula: = - log 10 H +. Some textbooks use [H3O+] to refer to the concentration of protons instead of [H + ]. Webb23 mars 2024 · On a scale of 1 to 14, a pH less than 7.0 is acidic, 7.0 is neutral, and anything higher than 7.0 is alkaline. Acidic or alkaline soil isn't necessarily bad; it all depends on the plants you're growing. 1 Most plants can adapt to soil pH ranges from 6 to 7.5, but some have distinct requirements.
