The pH at which the average charge is zero is known as the molecule's isoelectric point. Ampholytes are used to establish a stable pH gradient for use in isoelectric focusing . Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides. See more In chemistry, an amphoteric compound (from Greek amphi- 'both') is a molecule or ion that can react both as an acid and as a base. What exactly this can mean depends on which definitions of acids and bases are being used. See more Amphoteric is derived from the Greek word amphoteroi (ἀμφότεροι) meaning "both". Related words in acid-base chemistry are amphichromatic and amphichroic, both describing substances such as acid-base indicators which give one colour on … See more • Ate complex • Isoelectric point • Zwitterion See more According to the Brønsted-Lowry theory of acids and bases, acids are proton donors and bases are proton acceptors.

WebApr 11, 2024 · In contrast, amphoteric-type HMs, particularly Pb and Cr(Ⅲ), are mainly controlled by the sorption of C–S–H, AFt, and AFm at high pH. For anion-type HMs, the leaching of CrO 4 2− is primarily controlled by AFm sorption at high pH, while the leaching of AsO 4 3− is mostly controlled by sorption initially and by Ca 3 (AsO 4 ) 2 and ...
