Because primary key constraints guarantee … WebpH = pK a + 1 When [salt] / [Acid] = 1/10 then, pH = pK a – 1 Note: So weak acid may be used for preparing buffer solutions having pH values lying within the ranges pK a + 1 and pK a – 1. The acetic acid has a pK a of about 4.8. It may therefore be used for making buffer solutions with pH values lying roughly between the range 3.8 to 5.8. WebpK is defined as: pK = -log 10 K So we can convert pK values into K values using the relationship: K = 10 -pK Some special relationships between K and pK are given below: For water at 25°C and atmospheric pressure: K w = 10 −14 = [H +(aq) ] [OH -] pK w = 14.00 = pH + pOH For acids: ⚛ the stronger the acid the larger its K a but the smaller its pK a potting classes near me
