Another important group of amphiprotic species is the amino acids. Note: V 1 must be in the same units as V 2. There are 3 types salt-forming oxides: Basic oxides (from the word "Base"), acidic oxides and Amphoteric oxides. As a result, it will donate protons to the solution and make the. When an acid donates a proton to water, the water molecule is a proton acceptor, and hence a base. Buffers are systems that resist changes in pH by converting strong acids or bases to weak acids or bases. Classify these oxides as acidic, basic, amphoteric, or neutral.
