Web6 de abr. de 2024 · Cations in the soil are bound to negatively charged clay particles or the organic acids that form humus (see Soils), and this makes it difficult for plants to absorb them. Plants have a mechanism called cation exchange , which releases cations and frees them for absorption (figure \(\PageIndex{2}\)). WebReaction rates increase inversely with charge state and the total number of neutral molecules that add to the protein cations increases inversely with cation charge. These observations are inconsistent with the formation of proton-bound clusters but are fully consistent with the formation of ion pairs or dipole/dipole bonding involving the neutral … small reaper scythe crochet
