NettetThe hydration of negative ions When an ionic substance dissolves in water, water molecules cluster around the separated ions. This process is called hydration. Water frequently attaches to positive ions by co-ordinate (dative covalent) bonds. It bonds to negative ions using hydrogen bonds. Nettet9. mai 2024 · The kinetics of compatible pollen hydration turned out to be biphasic—a rapid hydration phase during the first 10 min is followed by a phase where there is little further hydration and pollen germination occurs (Rozier et al., 2024). Most incompatible pollen showed little sign of hydration (Rozier et al., 2024). martinelli expulso
