WebJan 27, 2024 · HH Equation: pH = pKa + log ( [Base] / [Acid]) For a buffer of pH 6.9, [Base] / [Acid] = 0.4898 Substitute for [Acid] and Solve for [Base] The desired molarity of the buffer is the sum of [Acid] + [Base]. For a 1 M buffer, [Base] + [Acid] = 1 and [Base] = 1 - [Acid] By substituting this into the ratio equation, from step 2, you get: WebSep 1, 2024 · The pH range of greatest phosphorus availability is 6.0 to 7.0. At a lower pH, when the soil is very acidic, more iron and aluminum are available to form insoluble phosphate compounds and, therefore, less phosphate is available. At very high pH, phosphorus can react with excess calcium to also form unavailable compounds in the … band am uol
