What is PH and why is it so important in Hydroponics?

WebSep 30, 2024 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. WebIf you are given the hydrogen ion concentration - [H +] - as power of 10, then the pH is just the number of the power (ignoring the - sign) e.g. [H +] = 10-8.5 gives you the pH as 8.5 If you are given the hydrogen ion concentration in standard form you can calculate the pH using the log function on a scientific calculator: [H +] = 3.2 x 10-9 M WebpH – The “Power” of Hydrogen.
