WebJan 27, 2024 · Stirring hotplate. Step 1. Decide on the Buffer Properties. Before making a buffer, you should first know what molarity you want it to be, what volume to make, and what the desired pH is. Most buffers work best at concentrations between 0.1 M and 10 M. The pH should be within 1 pH unit of the acid/conjugate base pKa. WebLooking at Table 5.2. 1, you see that the pK a of carboxylic acids are in the 4-5 range, the pK a of sulfuric acid is –10, and the pK a of water is 14. Alkenes and alkanes, which are not acidic at all, have pK a values above 30. The lower the pKa value, the stronger the acid. Table 5.2. 1: Representative acid constants.
