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: WebThe petitioner states that the amount of potassium hydroxide used should be limited to the amount necessary for emulsion of the fish and once the process is completed phosphoric acid will be used to stabilize the product.
