WebH3PO4, phosphoric acid, can be written O=P (OH)3. It has three acidic protons (attached to oxygen) and is therefore tribasic. Its salts are called phosphates. But H3PO3, phosphonic acid, has one of the hydrogens directly bound to phosphorus as O=PH (OH)2. This means that only two hydrogens are available to act as acids. Web27 jan. 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.
