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: At pH 1 or lower, the phosphoric acid is practically undissociated. Around pH 4.7 (mid-way between the first two pK a values) the dihydrogen phosphate ion, [H 2 PO 4] −, is practically the only species present.

WebUnder neutral pH and normal room temperatures, this hydrolysis is relatively slow. At 20o C and a pH of 7, about 50% of pyrophosphate (the shortest polyphosphate) will revert to orthophosphate in 12 years. At 50o C, the half-life is reduced to two months. Generally, lower pH and higher temperatures will increase the rate of hydrolysis.
